P.V=n.R.T this is the equation used for ideal gases.This equation gives the state of real gases approx.

The more accurate equation for real gases is by van der Waals ( P+a/v²).(v-b)=R.T

v=V/n=molar volume,R=0.08207 lt.atm/mol.K ideal gaz constant,a=3.592,b=0.04267,T=320 K,P=2.2 atm

write a program that finds the volume of v (molar volume) of 1 mol of carbon monoxide gas in a container at T = 320 K temperature and P = 2.2 atm pressure and compares the ideal gas equation with p.v = n.r.t

please could you write in a c++ ?
