The Henry's Law constant of methyl bromide, $C{H}_{3}Br,$ is $k=0\mathrm{.}159mo\frac{l}{L*atm}$ at $25C.$ What is the solubility of methyl bromide in water at $25C$ and at a partial pressure of $255.mmHg?$

$42\mathrm{.}9mo\frac{l}{L}$

$0\mathrm{.}382mo\frac{l}{L}$

$0\mathrm{.}0533mo\frac{l}{L}$

$0\mathrm{.}403mo\frac{l}{L}$
