Question 1

How many moles of water (H2O) are present in a 36.0-gram sample of pure water? (Molar mass of H2O = 18.0 g/mol)

18.0 moles 0.5 moles 2.0 moles 36.0 moles

Correct Answer:

2.0 moles

Question 2

According to the balanced chemical equation CH4 + 2O2 -> CO2 + 2H2O, how many moles of oxygen gas (O2) are required to completely react with 3.0 moles of methane (CH4)?

12.0 moles 1.5 moles 6.0 moles 3.0 moles

Correct Answer:

6.0 moles

Question 3

If 2.0 moles of N2 and 3.0 moles of H2 are mixed to react according to N2 + 3H2 -> 2NH3, which substance is the limiting reactant?

NH3 is the limiting reactant because it is the product being formed. H2 is the limiting reactant because it is completely consumed first. Neither substance is limiting because both are present in equal stoichiometric proportions. N2 is the limiting reactant because it has a smaller initial number of moles.

Correct Answer:

H2 is the limiting reactant because it is completely consumed first.

Question 4

A chemist calculates that a reaction should theoretically yield 50.0 grams of product. After performing the experiment, the actual yield collected is 42.5 grams. What is the percent yield of the reaction?

15.0% 42.5% 85.0% 117.6%

Correct Answer:

85.0%

Question 5

What volume does 1.00 mole of an ideal gas occupy at Standard Temperature and Pressure (STP: 0 deg C and 1.00 atm)?

1.00 liter 24.5 liters 22.4 liters 100.0 liters

Correct Answer:

22.4 liters
