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)0.041
B)0.014
C)0.31
D)0.12
E)3.0

Question

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 is tripled from 1.0 atm to 3.0 atm, the solubility will also triple: 0.041 g/L * 3 = 0.123 g/L, which is approximately 0.12 g/L.
