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 5.0 atm is __________ M. A)0.0035 B).00086 C)120 D)0.00055 E)5.0

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. Therefore, if the pressure increases from 1.0 atm to 5.0 atm, the solubility will increase by the same factor: 6.9 × 10^-4 M × 5 = 0.00345 M, which is approximately 0.0035 M.
