Sample of liquid ethanol, osorbs $5.13 \times 10^{3} \mathrm{~J}$ of heat at its normal boiling point, $78.0^{\circ} \mathrm{C}$. The molar enthalpy of vaporization of ethanol, $\Delta H_{\text {vap }}$, is $39.3$ $\mathrm{kJ} / \mathrm{mol}$. (a) What volume of $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$ vapor is produced? The volume is measured at $78.0^{\circ} \mathrm{C}$ and $1.00 \mathrm{~atm}$ pressure. (b) What mass of $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$ remains in the liquid state?A A $15.0$ -g sample of liquid ethanol, $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$, absorbs $5.13 \times 10^{3} \mathrm{~J}$ of heat at its normal boiling point, $78.0^{\circ} \mathrm{C}$.
