A $0.030-\mathrm{m}^{3}$ container is initially evacuated. Then, 4.0 $\mathrm{g}$ of water is placed in the container, and, after some time, all the water evaporates. If the temperature of the water vapor is $388 \mathrm{K},$ what is its pressure?

Step 1
To do this, we need to use the formula: $n = \frac{m}{M}$ where $n$ is the number of moles, $m$ is the mass of the substance, and $M$ is the molar mass of the substance. The molar mass of water is 18.015 g/mol. Therefore, the number of moles of water vapor Show moreā¦
