The solubility of oxygen gas in water at 25 °C and 1.0 atm pressure of oxygen is 0.041 g/L. The solubility of oxygen in water at 3.0 atm and 25 °C is g/L.
A) 3.0
B) 0.12
C) 0.31
D) 0.014
E) 0.041

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. If the pressure is increased from 1.0 atm to 3.0 atm, the solubility will also increase by the same factor. Therefore, 0.041 g/L * 3 = 0.123 g/L, which is approximately 0.12 g/L.
