Vinyl chloride (H2C=CHCl), the starting material from which PVC polymer is made, has a Henry's-law constant of 0.091mol/(L⋅atm) at 25 ∘C.

What is the solubility of vinyl chloride in water (in mol/L) at 25 ∘C and a partial pressure of 0.90atm ?

Sorry about that. So you've never used Henry's law before in class?

C is the solubility of a gas at a fixed temperature in a particular solvent (in units of M or mL gas/L)
k is Henry's law constant (often in units of M/atm)
Pgas is the partial pressure of the gas (often in units of Atm)
