Chapter 1, Problem 1.18NP

A mixture of $\text{2}.\text{1}0\times \text{1}{0}^{-\text{3}}\text{g}$ of ${\text{O}}_{\text{2}}$, $\text{3}.\text{88}\times \text{1}{0}^{-\text{3}}\text{mol}$ of ${\text{N}}_{\text{2}}$, and $\text{5}.\text{25}\times \text{1}{0}^{\text{2}0}$ molecules of CO are placed into a vessel of volume 5.25 L at $\text{12}.\text{5}°\text{C}$.

1. Calculate the total pressure in the vessel.
2. Calculate the mole fractions and partial pressures of each gas.
