Problem: A 500.0 ml sample of pure water is allowed to come to equilibrium with pure oxygen gas at a pressure of 755 mmHg. What mass of oxygen gas dissolves in the water? (The Henrys law constant for oxygen gas is 1.3 x 10-3 M/atm.)

FREE Expert Solution

Recall that the solubility of a gas is given by Henry’s law:


Sgas=kH·Pgas

where:

 Sgas = solubility of the gas (in mol/L or M)

kH = Henry’s law constant for the gas

Pgas = partial pressure of the gas
