Question

A 4.98 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter with a heat capacity of 4.25 kJ/°C. If the temperature rose from 29.5°C to 69.8°C, determine the value of ΔH°comb for aniline.

Answer 1

delta H = qcal*delta T for a 4.98g sample.
(delta H/4.98) = delta H in kJ/g. Multiply by molar mass to convert to kJ/mol.

Answer 2

-7.81 × 103 kJ/mol

Answer 3

answer is -3.2*10^3 KJ/moles katie your an idiot....

Answer 4

7.84 * 10^3

Answer 5

katie youre dumb. its -3.2*10^3

Answer 6

HAHAHAHAHAHAHAHA!!!!!!11!1!!one1! that's hilarious... but the answer is -3.2*10^3

Answer 7

None of these responses help
