of moles ,n = 21 mol, Pressure P = 78 atm, Temperature T = 900 K, Volume V = ?

We have to calculate the volume of the given moles of gas at specific temperature and pressure.

Using Ideal Gas equation;

PV = nRT

V = nRT /P ( R = gas constant = 0.08206 L atm

x 900K / 78 atm

V= 73.854 L atm / 78 atm = 0.946 L
