Step 1
First, we need to find the moles of water (H2O) in 0.770 L. We know that the density of water at 298 K is approximately 1 g/mL (or 1 g/cm³), and its molar mass is 18.015 g/mol. Show more…

The heat of combustion of $\mathrm{CH}_{4}$ is $890.4 \mathrm{kJ} / \mathrm{mol},$ and the heat capacity of $\mathrm{H}_{2} \mathrm{O}$ is 75.2 $\mathrm{J} / \mathrm{mol} \cdot \mathrm{K}$ . Find the volume of methane measured at 298 $\mathrm{K}$ and 1.00 atm required to convert 1.00 $\mathrm{L}$ of water at 298 $\mathrm{K}$ to water vapor at 373 $\mathrm{K}$ .
Calculate the pressure of 0.76 moles of methane that occupies 2800 cm3 at a temperature of 290 K.
