Stearic acid [{CH}_{3}({CH}_{2})_{16} {CO}_{2} {H}] is a fatty acid, the part of fat that stores most of the energy. 1.0 {g} of stearic acid was burned in a bomb calorimeter. The bomb had a heat capacity of 652 {J} \/{ }^\circ{C}. If the temperature of 500 {g} water ({c}=4.18 {J} \/ {g}^\circ {C}) rose from 25.0 to 39.3^\circ{C}, how much heat was released when the stearic acid was burned? [given {C}_{{p}}=({H}_{2} {O})=4.18 {J} \/ {g}^\circ{C}]

Marks: +1, -0

Stearic acid [CH3(CH2)16CO2H] is a fatty acid, the part of fat that stores most of the energy. 1.0g of stearic acid was burned in a bomb calorimeter. The bomb had a heat capacity of 652J∕‌°C. If the temperature of 500g water (c=4.18J∕g°C) rose from 25.0 to 39.3°C, how much heat was released when the stearic acid was burned?
[given Cp=(H2O)=4.18J∕g°C]
