A solution contains an unknown amount of dissolved magnesium. Addition of
0.0877 mol of Na2CO3 causes complete precipitation of all of the magnesium.
What mass of magnesium was dissolved in the solution?

Answers

Taking into account the reaction stoichiometry, 2.13 grams of magnesium was dissolved in the solution.

Reaction stoichiometry

In first place, the balanced reaction is:

Mg²⁺(aq) + Na₂CO₃(aq) → MgCO₃(s) + 2 Na⁺(aq)

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Mg²⁺: 1 mole Na₂CO₃: 1  moleMgCO₃: 1 moleNa⁺: 2 moles

The molar mass of the compounds is:

Mg²⁺: 24.3 g/moleNa₂CO₃: 106 g/moleMgCO₃: 84.3 g/moleNa⁺: 23 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

Mg²⁺: 1 mole ×24.3 g/mole= 24.3 gramsNa₂CO₃: 1 mole ×106 g/mole= 106 gramsMgCO₃: 1 mole ×84.3 g/mole=84.3 gramsNa⁺: 2 moles ×23 g/mole= 46 grams

Mass of magnesium dissolved

The following rule of three can be applied: If by reaction stoichiometry 1 mole of Na₂CO₃ react with 24.3 grams of magnesium, 0.0877 moles of Na₂CO₃ react with how much mass of magnesium?

[tex]mass of magnesium=\frac{0.0877 moles of Na_{2}C O_{3}x24.3 grams of magnesium }{1 mole of Na_{2}C O_{3}}[/tex]

mass of magnesium= 2.13 grams

Finally, 2.13 grams of magnesium was dissolved in the solution.

Ethanoic acid has a pKa of 4.75. Find the pH of the solutions that results from the addition of 40.0 mL of 0.040 M NaOH to 50.0 mL of 0.075 M ethanoic acid.

Answers

Answer:

About 4.63.

Explanation:

The reaction between ethanoic acid (CH₃COOH) and sodium hydroxide (NaOH) can be described by the following net ionic equation:

[tex]\displaystyle \text{CH$_3$COOH}_\text{(aq)} + \text{OH}^-_\text{(aq)}\longrightarrow \text{CH$_3$COO}^-_\text{(aq)} + \text{H$_2$O}_\text{($\ell$)}[/tex]

40.0 mL of 0.040 M NaOH contains:
[tex]\displaystyle 40.0\text{ mL} \cdot \frac{0.040\text{ mol NaOH}}{1000\text{ mL}} = 0.0016\text{ mol NaOH}[/tex]

Because NaOH is a strong base, it dissociates completely. Hence, the amount of OH⁻ present is 0.0016 mol. Na⁺ acts as a spectator ion.

50.0 mL of 0.075 M CH₃COOH contains:
[tex]\displaystyle 50.0\text{ mL} \cdot \frac{0.075\text{ mol CH$_3$COOH}}{1000\text{ mL}} = 0.0038\text{ mol CH$_3$COOH}[/tex]

OH⁻ is the limiting reagent of the reaction. Therefore, as the reaction proceeds to completion:

The amount of OH⁻ drops to 0 mol. The amount of CH₃COOH decreases to (0.0038 - 0.0016) mol = 0.0022 mol. And the amount of CH₃COO⁻ increases to (0 + 0.0016) mol = 0.0016 mol.

Note that all species present are in a one-to-one ratio.

To find pH, we can use the Henderson-Hasselbalch equation:

[tex]\displaystyle \text{pH} = \text{p}K_a + \log\frac{[\text{Base}]}{[\text{Acid}]}[/tex]

The total volume of the solution is 40.0 mL + 50.0 mL = 90.0 mL.

Hence, find [CH₃COOH]:

[tex]\displaystyle \left[\text{CH$_3$COOH}\right] = \frac{0.0022\text{ mol}}{90.0\text{ mL}} \cdot \frac{1000\text{ mL}}{1\text{ L}} = 0.024\text{ L}[/tex]

Find [CH₃COO⁻]:
[tex]\displaystyle \left[\text{CH$_3$COO}^-\right] = \frac{0.0016\text{ mol}}{90.0\text{ mL}}\cdot \frac{1000\text{ mL}}{1\text{ L}} = 0.018\text{ M}[/tex]

Therefore, the pH of the resulting solution is:
[tex]\displaystyle \begin{aligned}\text{pH} & = \text{p}K_a + \log\frac{[\text{Base}]}{[\text{Acid}]} \\ \\ & = (4.75) + \log \frac{(0.018)}{(0.024)} \\ \\ & = 4.75 + (-0.12) \\ \\ & = 4.63\end{aligned}[/tex]

In conclusion, the pH of the resulting solution is about 4.63.

Oleic acid, a component of olive oil, is 76.54% C, 12.13% H, and 11.33% 0. The
experimental value of the molar mass is 282 g/mol.
a. What is the molecular formula of oleic acid?
b. If oleic acid has a density of 0.895 g/mL, how many molecules of oleic acid
are in 3.00 mL of oleic acid?

Answers

Answer:

a) The molecular formula of oleic acid is: [tex]C_{18}H_{34}O_{2}[/tex]

b) There are 5.74 x 10^21 molecules of oleic acid in a 3.00 mL sample.

Explanation:

a)

First, let's determine the empirical formula of oleic acid from the percentage composition provided by the question:

- Assuming a 100g sample of oleic acid, the correspondent mass of C, H and O would be:

mass of C = 76.54g

mass of H = 12.13g

mass of O = 11.33g

- We must determine the number of moles contained in each of the masses determined above. For that, let's use the atomic masses of C (12.01 u), H (1.007 u) and O (15.99 u) and the following equation:

[tex]number of moles = \frac{mass of sample}{molar mass}[/tex]

number of moles of C = 76.54g / 12.01 g/mol = 6.373 mol C

number of moles of H = 12.13g / 1.007 g/mol = 12.04 mol H

number of moles of O = 11.33g / 15.99 g/mol = 0.7086 mol O

- Next, we'll try to find whole-number ratios by dividing each number of moles obtained by the smallest value obtained (0.7086):

C = 6.373 / 0.7086 = 8.994 ≅ 9

H = 12.04 / 0.7086 = 16.99 ≅ 17

O = 0.7086 / 0.7086 = 1.000

- Now, we can write the empirical formula of oleic acid as: [tex]C_{9}H_{17}O[/tex]

Now that we have the empirical formula for oleic acid (C9H17O), let's check its molar mass and compare it to the experimental value provided by the question (282 g/mol):

molar mass (C9H17O) = 9 * 12.01 + 17 * 1.007 + 1 * 15.99 = 141.9 g/mol

Note that the molar mass obtained from the empirical formula (141.9 g/mol) and the experimental molar mass (282 g/mol) are different, thus we need to find an integer multiple to determine the molecular formula (keep in mind that molecular formulas always present kind and number of atoms of each element present in the molecular compound, while the empirical formula presents the smallest coefficients for each atom).

Molecular formula = n × Empirical formula

This integer multiple, n, can  be obtained by dividing the molar mass,  MM , of the compound by the empirical formula mass,  EFM  (the molar mass represented by the empirical formula):

n = MM / EFM

n = 282 / 141.9

n = 1.987 ≅ 2

Since the integer multiple is 2, we can multiply all coefficients in the empirical formula by 2 to find the molecular formula of oleic acid:

C9 H17 O x 2 = C18 H34 O2

Therefore, the molecular formula of oleic acid is: [tex]C_{18}H_{34}O_{2}[/tex]

b)

We need to calculate the amount of molecules of oleic acid in a 3.00mL sample, considering the density as 0.895 g/mL.

From the density provided, we can calculate the mass, in grams, of oleic acid contained in 3.00 mL of this compound:

1 mL ----------------------- 0.895 g oleic acid

3.00 mL ----------------- x

Solving for x, we have that there are 2.69 g of oleic acid in a 3.00 mL sample.

Next, considering the molar mass of oleic acid (282 g/mol), we can calculate the number of moles contained in 2.685g of the acid:

282 g -------------------- 1 mol oleic acid

2.69 g ----------------- y

Solving for y, we have that there are 0.00953 moles of oleic acid in a 3.00 mL sample.

Now, using the Avogadro's number (6.022 x 10^23 particles/mol), we can calculate the amount of molecules of oleic acid in the sample:

1 mol oleic acid ------------------------------- 6.022 x 10^23 molecules oleic acid

0.00953 mol oleic acid ------------------- z

Solving for z, we have that there are 5.74 x 10^21 molecules of oleic acid in a 3.00 mL sample.
