Question

What is the equation of gas in terms of pressure (P), absolute temperature (T) and density (d)?

Answer 1

The Ideal Gas equation........

Explanation:

`PV=nRT`, and thus `P/(RT)=n/V`

But `n="mass"/"molar mass"`,

And thus `P/(RT)=("mass"/"molar mass")/V`

And finally, `P/(RT)xx"molar mass"="mass"/V=rho_"gas"`
