A 655 G Sample of Aniline (C₆H₅NH₂, Molar Mass = 93

question 33

Multiple Choice

A 6.55 g sample of aniline (C₆H₅NH₂, molar mass = 93.13 g mol^-1) was combusted in a bomb calorimeter with a heat capacity of 14.25 kJ °C^-1. If the initial temperature was 32.9 °C, use the information below to determine the value of the final temperature of the calorimeter. 4C₆H₅NH₂(l) + 35O₂(g) → 24CO₂(g) + 14H₂O(g) + 4NO₂(g)
Δ_rU° = -1.28 × 10⁴ kJ mol^-1

• A)257 °C
• B)46.6 °C
• C)96.1 °C
• D)41.9 °C
• E)931 °C
