How to solve

$19\mathrm{.}26*$ For an ideal gas $C_V$ and $C_p$ are different because of the work $W$ associated with the volume change for a constant$-$pressure process. To explore the difference between $C_V$ and $C_p$ for a liquid or a solid, consider the process in which $5\mathrm{.}00$ mol of ethanol is warmed from $10\mathrm{.}0C$ to $60\mathrm{.}0C$ while the applied pressure remains a constant $1\mathrm{.}00$ atm $.$ The molar mass of ethanol is $M=46\mathrm{.}1\frac{g}{m}ol.($a$)$ What is the mass of $5\mathrm{.}00$ mol of ethanol? $($b$)$ How much heat $Q$ enters the ethanol? $($c$)$ How much work $W$ is done by the ethanol because of its thermal expansion? $($d$)$ What is the ratio $\frac{W}{Q}?$
