Suppose you burned $0\mathrm{.}300g$ of

$C(s)$ in an excess of

$O_2(g)$ in a constant$-$volume calorimeter to give

$C{O}_2(g).$

$C(s)+O_2(g)C{O}_2(g)$

The temperature of the calorimeter, which contained $715g$ of water, increased from $26\mathrm{.}40C$ to $28\mathrm{.}95C.$ The heat capacity of the bomb is $871\frac{J}{K}.$ Calculate $U$ per mole of carbon. $($The specific heat capacity of liquid water is $4\mathrm{.}184\frac{J}{g}*K.)$

$U=,k\frac{J}{m}$olC
