A generic solid, $x,$ has a molar mass of $79\mathrm{.}4\frac{g}{m}ol.$ In a constant$-$pressure calorimeter, $22\mathrm{.}5g$ of $x$ is dissolved in $321g$ of water at $23\mathrm{.}00C.$

$x(s)x(aq)$

The temperature of the resulting solution rises to $24\mathrm{.}10C.$ Assume the solution has the same specific heat as water, $4\mathrm{.}184\frac{J}{g*C},$ and that there is negligible heat loss to the surroundings.

How much heat was absorbed by the solution?

$q=$

What is the enthalpy of the reaction?

$H_{rnn}=$
