(B) According to Graham's Law of Diffusion,the rate of diffusion $(r)$ is inversely proportional to the square root of the density $(d)$: $r_1 / r_2 = \sqrt{d_2 / d_1}$ Given: $r_H = 1$ $d_H = 0.09 \ g \ L^{-1}$ $d_O = 1.44 \ g \ L^{-1}$ Substituting the values: $r_H / r_O = \sqrt{d_O / d_H}$ $1 / r_O = \sqrt{1.44 / 0.09} = \sqrt{16} = 4$ $r_O = 1 / 4 = 0.25$
