# Can I interpret Avogadro's principle of gases from the state equation (ideal gas law)?

Considering the molar form of the ideal gas law I can solve for the ratio of some gas volume, $V$ divided by the number of gas particles, $n$ in mols $$\frac{V}{n}=\frac{RT}{P}$$

And $R$ is the Universal Gas Constant

So then if I roughly have 1 mol of gas occupying 22.4 liters of space (the gas 'volume') then I can expect that the temperature, $T$ and pressure, $P$ on the right side of the equation are at the standard values.

Is this interpretation right?

• $T$ and $p$ can both vary here as long as their ratio is constant. – march Jun 26 '15 at 20:19
• @march good point. I suppose then that underlines a fact that 'standard ' temperature and pressure are somewhat an arbitrary choice. But the ratio must be specific. – docscience Jun 27 '15 at 13:26
