Chapter 11, Problem 90E

Interpretation Introduction

Interpretation:

The moles of ${\text{H}}_2\text{O}$ that would be required to form 1.3 L $O_2$ at 325 K and 0.988 atm is to be calculated.

Concept introduction:

Amount of the gas can be specified in terms of its volume at specific temperature and pressure in reactions involving gaseous reactants or products.

In cases like above, ideal gas law can be used to convert temperature, pressure and volume to number of moles.

Expression of ideal gas is:

$n=\frac{PV}{RT}$

Here, $P$ is pressure, $V$ is volume, $R$ is gas constant and $T$ is temperature.
