# What does the ideal gas law allow a scientist to calculate that the other gas laws do not?

Feb 29, 2016

It allows for the calculation of moles

#### Explanation:

$P V = n R T \to$ the ideal gas law equation

Here $n$ represents the number of moles of gas.

${P}_{1} {V}_{1} = {P}_{2} {V}_{2} \to$ the equation for Boyle's Law

$\frac{{P}_{1} {V}_{1}}{T} _ 1 = \frac{{P}_{2} {V}_{2}}{T} _ 2 \to$ the combined gas law equation

${P}_{1} / {T}_{1} = {P}_{2} / {T}_{2} \to$ the equation for Gay Lussac's Law

None of the other gas laws include the number of moles of gas in their calculation
