just when i thought i was done with my chem homework...?

Question

i can't remeber how to do this problem:

The solubilityof methane, the major component of natural gas, in water at 20 degrees C and 1.00 atm pressure is 0.026 g/L. If the temperature remains constant, what will be the solubility of this gas at the following pressures:
a. 0.60atm
b. 1.80atm


u don't need to spend the time solving it... can you just tell me the formula? i can't remember it =P

thanks!
