Using Table 5.4 in the textbook, we can determine the vapor pressure of water.

*According to** Dalton’s Law,** the **total pressure is the sum of partial pressures of each gas: *

$\overline{){{\mathbf{P}}}_{\mathbf{t}\mathbf{o}\mathbf{t}\mathbf{a}\mathbf{l}}{\mathbf{=}}{{\mathbf{P}}}_{\mathbf{G}\mathbf{a}\mathbf{s}\mathbf{}\mathbf{1}}{\mathbf{+}}{{\mathbf{P}}}_{\mathbf{G}\mathbf{a}\mathbf{s}\mathbf{}\mathbf{2}}{\mathbf{+}}{{\mathbf{P}}}_{\mathbf{G}\mathbf{a}\mathbf{s}\mathbf{}\mathbf{3}}{\mathbf{.}}{\mathbf{.}}{\mathbf{.}}}$

How can the partial pressure of the collected gas be determined?
