USING HENRY’S LAW TO CALCULATE GAS SOLUBILITY

The Henry’s-law constant of methyl bromide ( $CH_{3}Br$ ), a gas used as a soil fumigating agent, is k = 0.159 mol/(L · atm) at 25 °C. What is the solubility in mol/L of methyl bromide in water at 25 °C and a partial pressure of 125 mm Hg?

STRATEGY
According to Henry’s law, solubility = k · P.
