A rectangular block weighs 121g. The dimensions of the block are 9.1cm by 5.4cm by 2.3cm. From this data, what us the density of the block in g/mL? Will tge block float or sink in water and how do you know? Show all your work on a piece of paper.​

Answers

The density of the rectangular block is 1.07 g/mL.

From the question, we have the mass of the rectangular block as 121g

The dimensions of the block are given as follows;9.1cm by 5.4cm by 2.3cm

So we have the volume of the block as; 9.1cm × 5.4cm ×  2.3cm = 113 cm^3

Let us recall that; 1 cm^3 = 1 mL, so 113 cm^3 = 113 mL

Having said that, we must also remember that;

Density = Mass/volume

Density = 121g/113 mL

Density = 1.07 g/mL

A solution made from pure Potassium hydroxide contained 1.85 g of Potassium hydroxide in exactly 200 cm3 of water. Using phenolphthalein indicator, titration of 20.0 cm3 of this solution is carried out v/s sulphuric acid. 9.35 cm3 of sulphuric acid solution is required for complete neutralisation. [atomic masses: K= 39, O = 16, H = 1]
(a) write the equation for the titration reaction.
(b) calculate the molarity of the Potassium hydroxide solution. (c) calculate the moles of Potassium hydroxide neutralised. (d) calculate the moles of sulphuric acid neutralised.
(e) calculate the molarity of the sulphuric acid.

Answers

The concentration of H2SO4 is  0.176 M. The number of moles of H2SO4 is 0.0165 moles.

The equation of the reaction is;

2KOH(aq) + H2SO4(aq) ------> K2SO4(aq) + H2O(l)

The number of moles of KOH = 1.85 g/56 g/mol = 0.033 moles

concentration = number of moles /volume

volume = 200 cm3 or 0.2 L

concentration of KOH = 0.033 moles/0.2 L = 0.165 M

From the titration formula;

CAVA/CBVB =na/nb

CA = concentration of acid

VA = volume of acid

CB = concentration of base

VB = volume of base

na = number of moles of acid

nb = number of moles of base

Making CA the subject of formula;

CA = CBVBna/VAnb

CA = ?

CB = 0.165 M

VA =  9.35 cm3

VB = 20.0 cm3

na = 1

nb =2

CA = CBVBna/VAnb

CA = 0.165 M ×  20.0 cm3  × 1/9.35 cm3 × 2

CA = 0.176 M

The concentration of sulphuric acid is 0.176 M

From the reaction equation;

2 moles of KOH reacts with 1 mole of H2SO4

0.033 moles of KOH reacts with 0.033 moles ×  1 mole/2 moles

= 0.0165 moles of H2SO4

Explanation:

Number of electrons = Number of protons. Originally, sulfur has 16 protons, but the question asks states 2- ions. So S^(2-), or a total of 18 protons. Follow the rules, and make sure the exponents add up to 18. 2 + 2 + 6 + 2 + 6 = 18 electrons.
