The heat of combustion of benzoic acid c6h5cooh is -3226, Ask an Expert

Academics

The heat of combustion of benzoic acid (C6H5COOH) is -3226 kJ/mol at constant volume. When a sample of benzoic acid was burned in a bomb calorimeter having a calorimeter constant of 12.5 kJ/oC, the temperature of the calorimeter (including its contents) rose from 23.18oC to 27.65oC. What mass, in g, of benzoic acid was burned? here is what i did, 3226/122.13=26.41 delta t =4.474 so 4.474*12.5/26.41 =2.12 is the answer 2.12g?
