Chapter 5, Problem 60E

Interpretation Introduction

Interpretation:Volume of ${\text{H}}_2$ and air required to produce pure molybdenum from ${\text{MoS}}_{\text{2}}$ is to be calculated.

Concept introduction: The expression to determine number of moles is as follows:

  $\text{Number of moles}=\frac{\text{Given Mass}}{\text{Molar mass}}$

The formula to calculate volume as per ideal gas law is as follows:

  $V=\frac{nRT}{P}$

Where,

• $R$ is gas constant.
• $V$ denotes the volume.
• $n$ denotes number of moles.
• $T$ denotes temperature.
• $P$ denotes pressure.
