Chapter 2, Problem 25P

Disilane $\left({\text{Si}}_{\text{2}}{\text{H}}_{\text{6}}\right)$ is a gas that reacts with oxygen to givesilica $\left({\text{SiO}}_{\text{2}}\right)$ and water. Calculate the mass of silica thatwould form if $\text{25}.0{\text{ cm}}^{\text{3}}$ disilane (with a density of $\text{2}.\text{78}\times \text{1}{0}^{-\text{3}}{\text{g cm}}^{-\text{3}}$ ) reacted with excess oxygen.
