Question

Based on the observations below, calculate the molar enthalpy of combustion (∆H_comb) of compound X

Volume of Water	800 ml	Final Temp of water	72.8^oC
Mass of gold calorimeter	63.5 g	Initial mass of compound X	39.5 g
Initial Temp of water	29.5^oC	Final mass of compound X	32.6 g

The molar mass of compound X is 87.26 g/mol

Your answer should follow the format:

a) q_water
b) q_calorimeter
c) q_total
d) mass compound X
e) mols compound X

f)∆H_comb of compound X with units
