QUESTION 1:

An acid contains 68.85% carbon, 4.92% hydrogen and 26.23% oxygen. Its empirical formula is the same as its molecular formula. The number of hydrogen atoms in this molecule is:

a.) 6

b.) 4

c.) 2

d.) 3

Question 2:

Use the following reaction and molar mass (MM) data to answer the question:

2C3H7OH + 9O2 --> 6CO2 + 8H2O

MM of C3H7OH = 60.0 g/mol
MM of O2 = 32.0 g/mol
MM of CO2 = 44.0 g/mol
MM of H2O = 18.0 g/mol

In a reaction vessel, 15g of C3H7OH and 28g of O2 are mixed and allowed to react. Which reactant acts as the limiting reagent?

a.)C3H7OH

b.) O2

c.) CO2

d.) H2O
