Chapter 5, Problem 5.32P

v

Interpretation Introduction

Interpretation: The number of moles of gaseous arsine and its density needs to be determined for given volume at STP.

Concept Introduction: An ideal gas equation is represented as follows:

  $PV=nRT$

Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas.

Density of a substance is defined as mass per unit volume.

It can be calculated from mass and volume as follows:

  $d=\frac{m}{V}$

Here, m is mass and V is volume.
