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

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

Explanation:

$P V = n R T$ $PV=nRT$ , and thus $\frac{P}{R T} = \frac{n}{V}$ $P/(RT)=n/V$

But $n = \frac{mass}{molar mass}$ $n="mass"/"molar mass"$ ,

And thus $\frac{P}{R T} = \frac{\frac{mass}{molar mass}}{V}$ $P/(RT)=("mass"/"molar mass")/V$

And finally, $\frac{P}{R T} \times molar mass = \frac{mass}{V} = ρ_{gas}$ $P/(RT)xx"molar mass"="mass"/V=rho_"gas"$
