Question
Calculate the solubility of nitrogen in blood for a scuba diver at a depth of 125 feet and a pressure of 4.68 atm. The solubility of nitrogen gas is $0.0019 \mathrm{~g} / 100 \mathrm{~g}$ blood at normal pressure.
Step 1
According to Henry's law, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. This means that as we increase the pressure of the gas, more of it will dissolve in the liquid. Show more…

The solubility of nitrogen gas is $1.90 \mathrm{~mL} / \mathrm{dL}$ of blood at 1.00 atm. What is the solubility of nitrogen gas in a scuba diver's blood at a depth of 125 feet and a pressure of 4.50 atm?
The solubility of nitrogen gas is $1.90 \mathrm{~mL} / \mathrm{dL}$ of blood at 1.00 atm. What is the solubility of nitrogen gas in a scuba diver's blood at a depth of 225 feet and a pressure of 8.00 atm?
Nitrogen, $\mathrm{N}_{2}$, is soluble in blood and can cause intoxication at sufficient concentration. For this reason, the U.S. Navy advises divers using compressed air not to go below 125 feet. The total pressure at this depth is 4.79 atm. If the solubility of nitrogen at $1.00 \mathrm{~atm}$ is $1.75 \times$ $10^{-3} \mathrm{~g} / 100 \mathrm{~mL}$ of water, and the mole percent of nitrogen in air is $78.1,$ what is the solubility of nitrogen in water from air at $4.79 \mathrm{~atm} ?$
