Question 1

If the density of ethanol, C2H5OH, is 0.789 g mL-1. How many millilitres of ethanol are needed to produce 15.0 g of CO2 according to the following chemical equation?

C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(l)

◦ 6.19 mL
◦ 9.95 mL
◦ 19.9 mL
◦ 39.8 mL

Question 2

If the percent yield for the following reaction is 65.0%, how many grams of KClO3 are needed to produce 32.0 g of O2?

2 KClO3(s) → 2 KCl(s) + 3 O2(g)

◦ 53.1 g
◦ 81.7 g
◦ 126 g
◦ 283 g
