What is the solubility of that same gas at 835 mmHg?

Question

The solubility of a gas is 2.3 g/L at 760 mmHg. What is the solubility of that same gas at 835 mmHg? temperature remains constant

Answer 1

This uses an application of Henry's law:

C1/P1 = C2/P2

C1 = initial concentration = 2.3 g/L

P1 = initial pressure = 760 mm Hg

C2 = final concentration = ?

P2 = final pressure = 835 mm Hg

2.3/760 = x/835

x = (2.3)(835) / 760

x = 2.53 g/L = solubility @ 835 mm Hg
