Chapter 8, Problem 8.101CP

Interpretation Introduction

Interpretation:

The volume of hydrogen required to react with $\text{2}\text{.5}\text{L}\text{of}{\text{O}}_{\text{2}}$ at STP should be determined for the given reaction.

Concept introduction:

Ideal gas law:

The gas law which relates the variables temperature, volume, pressure and the number of molecules and this law can be mathematically expressed as:

$\text{PV}\text{=}\text{nRT}$

It can also be defined as that one mole of any gas contains a volume of $\text{22}\text{.4}\text{L}$ at $\text{0°C}\text{and}\text{1}\text{atm}\text{pressure}$.

$\text{Number}\text{of}\text{moles}\text{=}\frac{\text{Volume}}{\text{22}\text{.4}\text{L}}$

The conditions of $\text{0°C}\text{and}\text{1}\text{atm}\text{pressure}$ is called as standard temperature and pressure $\left(\text{STP}\right)$

$\text{Density}\text{=}\frac{\text{mass}}{\text{volume}}$
