Question 1

An 8.21 g sample of glycerol (C3H8O3, molar mass = 92.0938 g mol-1) was combusted in a bomb calorimeter with a heat capacity of 10.61 kJ °C-1. If the temperature increased from 22.1 °C to 36.0 °C, determine DrU for the combustion of glycerol.
◦ -4.38 × 103 kJ mol-1
◦ -2.18 × 103 kJ mol-1
◦ 3.65 × 103 kJ mol-1
◦ 2.18 × 103 kJ mol-1
◦ -1.65 × 103 kJ mol-1

Question 2

Calculate the amount (mass) of acetic acid (C2H4O2, molar mass = 60.052 g mol-1) that causes a bomb calorimeter with a heat capacity of 8.43 kJ °C-1 to have a temperature increase from 24.5 °C to 36.8 °C. The DrU for the combustion of acetic acid is -874.2 kJ mol-1.
◦ 6.18 g
◦ 2.18 g
◦ 8.68 g
◦ 7.12 g
◦ 9.66 g
