Part A

Caloulate the mass of nitrogen ciissolved at room temperature in an $99\mathrm{.}0L$ home aquarium. Assume a total pressure of $1\mathrm{.}0$ atm and a mole fraction for nitrogen of $0\mathrm{.}78.$ The Henry's law constant for nitrogen at $25C$ is $6\mathrm{.}1{10}^{-4}\frac{M}{a}tm.$

Express your answer in grams to two significant figures.

First, use Henry's law to calculate the solubility of nitrogen in water. Then use solubility, which has the units mol$/L,$ as a conversion factor between the volume of water and the number of moles of dissolved nitrogen. Finally, use the molar mass of nitrogen $($in $\frac{g}{m}ol)10$ convert the number of moles to the mass in grams. No credit lost. Try again.
