Chapter 11, Problem 11.5P

How much heat is required to convert15.0 g of liquid benzene ( $C_6{H}_6$ ) at 50 C to gaseous benzene at 100 °C? The boiling point of benzene is 80.1 °C and $C_m\left[C_6{H}_6\left(l\right)\right]=\text{136}\text{.0 J/}\left(\text{mol}·°\text{C}\right),$
$\Delta H_{\text{vap}}=\text{30}\text{.72 kJ/mol,}$
$C_m\left[C_6{H}_6\left(g\right)\right]=\text{82}\text{.4 J/}\left(\text{mol}·°\text{C}\right)$
