Homework Statement

What is the solubility of an unknown gas in water at 1.0 atm if its solubility at 3.0 atm is 1.02M?

Homework Equations

Henry's law S_g = k*P_g

The Attempt at a Solution

S_g = 1.02M/3.0atm * 1.0 atm = .34 atm

I'm not sure if P_g, the partial pressure of the gas, is 1.0 atm or 3.0 atm.

Sg = 1.02M/3.0atm * 1.0 atm = .34 atm

Are the units correct?

.34 is in M instead of atm (I forgot to cancel out the atm).
