The solubility of nitrogen gas in water at 25 °C and a nitrogen pressure of 1.0 atm is 6.9 × 10^-4 M. The solubility of nitrogen in water at a nitrogen pressure of 2.0 atm is ________ M. A)0.0014 B)0.00086 C)120 D)0.0037 E)2.0

Question

Quizplus · Accepted Answer

According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. Doubling the pressure from 1.0 atm to 2.0 atm doubles the solubility from 6.9 × 10^-4 M to 1.38 × 10^-3 M, which is approximately 0.0014 M.
