The following information is given for ether, $C_2{H}_{5}O{C}_2{H}_5,$ at $1$atm :

boiling point $=34\mathrm{.}6C,H_{\text{v}\text{a}\text{p}}(34\mathrm{.}6C)=26\mathrm{.}5k\frac{J}{m}ol$

melting point $=-116C,H_{\text{f}\text{u}\text{s}}(-116C)=7\mathrm{.}27k\frac{J}{m}ol$

specific heat liquid $=2\mathrm{.}32\frac{J}{g}C,$

At a pressure of $1$atm, $kJ$ of heat are needed to vaporize a $36\mathrm{.}7g$ sample of liquid ether at its normal boiling point of $34\mathrm{.}6C.$
