Chapter 13, Problem 13.88P

Interpretation Introduction

Interpretation:

Mass percentage of $\text{NaH}$ and ${\text{CaH}}_{\text{2}}$ in the mixture has to be calculated.

Concept Introduction:

The expression to calculate $n$ as per the ideal gas equation is as follows:

  $n=\frac{PV}{RT}$

Here,

$R$ is the universal gas constant.

$V$ denotes the volume.

$n$ denotes the number of moles.

$T$ denotes the temperature.

$P$ denotes the pressure.

The formula to determine mass percent is as follows:

  $\text{Mass percent}\text{}\%=\frac{\text{Mass of metal}}{\text{Total mass of mixture}}\left(100\right)$
