Question 1

Using the following equation for the combustion of octane, calculate the amount of grams of carbon dioxide formed from 100.0 g of octane. The molar mass of octane is 114.33 g mol-1. The molar mass of carbon dioxide is 44.0095 g mol-1.
 
2C8H18 + 25O2 → 16CO2 + 18H2ODrH° = -11018 kJ

◦ 307.9 g
◦ 260.1 g
◦ 792.3 g
◦ 800.1 g

Question 2

What volume of benzene (C6H6, d = 0.88 g mL-1, molar mass = 78.11 g mol-1) is required to produce 1.5 × 103 kJ of heat according to the following reaction?

2C6H6(l) + 15O2(g) → 12CO2(g) + 6H2O(g)DrH° = -6278 kJ

◦ 42 mL
◦ 37 mL
◦ 21 mL
◦ 75 mL
◦ 19 mL
