How to convert the mass of a substance to the number of moles of a substance, and moles to mass
Answer:
Explanation:
To convert the mass to moles, divide the mass by the atomic weight of the element or compound.
To convert back to mass from the moles, multiply the moles by the atomic weight of the element or compound
2. If you have 8.08 g of hydrogen, how many grams of ammonia will your produce?
answer: Stoichiometry is a big word for a process that chemist’s use to calculate
amounts in reactions. It makes use of the coefficient ratio set up by balanced
reaction equations to make connections between the reactants and products
in reactions.
Stoichiometry calculates the quantities of reactants and products in a
chemical reaction. The equation must be balanced!
Questions that deal with amounts in reactions are examples of reaction
stoichiometry. We already have the tools necessary to solve this question.
We just need to learn a new way to apply skills such as writing chemical
formulas, calculating formula masses, and converting from mass to moles,
particles to moles, and volume of gases to moles.
Mole to Mole Conversions- you must have the Mole Ratio.
Illustration:
Let’s use an analogy that we can understand to begin to understand the process.
The KEY to any mole conversion is the ratio of coefficients in the reaction
equation. Say I want to make a bacon double cheeseburger. Let’s get our recipe
together.
1 hamburger bun + 2 hamburger patties + 2 slices of cheese + 4 strips of bacon →
1 bacon double cheeseburger
Based on this recipe:
1) If I have five bacon double cheeseburgers:
a. How many hamburger buns did you use? → 5 hamburger bun
b. How many hamburger patties did you use? → 10 hamburger patties
c. How many slices of cheese did you use? → 10 slices of cheese
d. How many strips of bacon did you use? → 20 strips of bacon
2) How many bacon double cheeseburgers can you make if you start with:
a. 2 buns, 4 patties, 4 slices of cheese, 8 strips of bacon
2 bacon double cheese burgers
b. 1 dozen buns, 2 dozen patties, 2 dozen slices of cheese, 4 dozen strips of bacon
1 dozen bacon double cheese burgers

If a sample of 0.500 moles of hydrogen sulfide (H2S) was reacted with excess concentrated sulfuric acid, how many moles of sulfur dioxide (SO2) would be produced?
Answer:
2.00
Explanation:
They said that was the answer.
If a sample of 0.500 moles of hydrogen sulfide H₂S was reacted with excess concentrated sulfuric acid then, number of moles of sulfur dioxide SO₂ would be produced are 2.00.
What are moles in gases?It is the ratio of mass of element in grams of a given compound and the molar mass of the element. In order to have balanced equation, we have to find the correct number of mole of SO₂. The reaction is
H₂S(g) + 3H₂SO₄ ⇄ 4H₂O(l) + 4SO₂
1 mole of H₂S react with excess of H₂SO₄ to give 4 moles of SO₂.
0.5 mole of H₂S react with excess of H₂SO₄ to give 4 x 0.5 =2.00 moles of SO₂.
Thus, 2 moles of sulfur dioxide SO₂ would be produced.

Carbohydrates like sugars and starches are made of only three elements: carbon (C), hydrogen (H), and oxygen (O). How is it possible that so many different carbohydrates can be formed using only these three elements?
Answer:
See explanation
Explanation:
A carbohydrate is formed from carbon, hydrogen and oxygen. These three elements are combined in every carbohydrate.
Even though carbohydrates are composed of only these three atoms, the number of atoms of these elements in each carbohydrate as well as the spatial arrangement of these atoms in each carbohydrate is not the same.
This means that different carbohydrates contain different number of carbon, oxygen and hydrogen atoms which are arranged in different ways in space. This gives room for the existence of many different types of carbohydrates all consisting of carbon, hydrogen and oxygen atoms.
The information regarding the different carbohydrates that should be formed is explained below.
Carbohydrates:It should be created from carbon, hydrogen, and oxygen. It should be combined with every carbohydrate. Still, carbohydrates should be comprised of only these three atoms, so the no of atoms of these elements in every carbohydrate also the spatial arrangement of these atoms in every carbohydrate is not similar.
This represents that various carbohydrates contain distinct numbers of carbon, oxygen, and hydrogen atoms that are in different ways in space.

C. The boiling temperature of the substance
D. The energy required to form a molecule
Answer:
B
Explanation:
a p e x
The specific heat of a substance represent the ability of a substance to hold heat. Therefore, the correct option is option B.
What is specific heat of a substance?The amount of heat needed to raise a substance's temperature by one degree Celsius in one gram, also known as specific heat. Typically, calories as well as joules for every gram per degree Celsius are used as the measures of specific heat.
The notion of specific heat was developed by the Scottish scientist William Black in the 18th century as a result of his discovery that identical quantities of different substances required varying quantities of heat to raise them within a comparable temperature range. The specific heat of a substance represent the ability of a substance to hold heat.
Therefore, the correct option is option B.

Why does lowering the pressure cause a liquid to boil?
A. It becomes easier for molecules to escape.
B. It pushes molecules out of the liquid.
C. It causes the temperature to rise.
D. It changes the volume of the liquid.
Lowering the pressure in a container will cause the liquid in the container to boil faster because it becomes easier for the molecules to escape.
What causes boiling?Boiling happens when the vapor pressure of a liquid equals the atmospheric pressure.
By lowering the atmospheric pressure, the vapor pressure of a liquid takes a lower time to equal the atmospheric pressure.
Thus, it becomes easier for the molecules of the liquid to escape from each other.

What mass of the protein gelatin is needed to make 0.5 L of a 3 g/L gelatin solution? Show your work.
Answer:
m = 1.5 gram
Explanation:
Given that,
Density of protein gelatin, d = 3 g/L
The volume of protein gelatin, V = 0.5 L
We need to find the mass of the protein gelatin. The density of an object is given by :
d = m/V
Where
m is mass
[tex]m=d\times V\\\\m=3\ g/L\times 0.5\ L\\\\m=1.5\ g[/tex]
