The Henry's Law constant for carbon tetrachloride is $0\mathrm{.}030m^{3}atmmo{l}^{-1}.$ The molecular weight of carbon tetrachloride is $153\mathrm{.}8\frac{g}{m}ol.$ If the partial pressure of carbon tetrachloride in the vapor phase is $0\mathrm{.}05$ in of $Hg,$ and the vapor phase is in equilibrium with water, the concentration of carbon tetrachloride in the water $(m\frac{g}{L})$ is most nearly:

A$)0\mathrm{.}003$

B$)8\mathrm{.}6$

C$)260$

D$)8600$
