A $3\mathrm{.}03-$g sample of stearic acid $(C_{18}{H}_{36}{O}_2)$ is burned in a constant$-$volume calorimeter that has a heat capacity of $10\mathrm{.}8k\frac{J}{}C.$ The

temperature increases from $16\mathrm{.}2C$ to $27\mathrm{.}3C.$

a$)$ Determine the amount of heat released $($in $kJ).$

k

b$)$ Determine the molar energy of combustion of stearic acid $($in $k\frac{J}{m}ol).$
