Chapter 3, Problem 100QRT

Interpretation Introduction

Interpretation:

$\text{6}\text{.22 g}$ Sample of silicon compound (${\text{Si}}_{\text{x}}{\text{H}}_{\text{y}}$) is burned in oxygen, the Si is converted to $\text{11}{\text{.64 g SiO}}_{\text{2}}$ and all $\text{H to 6}{\text{.980 g H}}_{\text{2}}\text{O}$. The empirical formula of silicon compound has to be calculated.

Concept introduction:

Number of moles can be calculated by using following formula,

  $\text{No}\text{.of Moles = }\frac{\text{Mass}}{\text{Molar}\text{mass}}$
