In this questions Pressure P = 1 atm, Temperature T = 546 K, Volume V = 11.2 L are given , we are asked to find out # of moles.

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

Using Ideal Gas equation;

PV = nRT

n = RT /PV ( R = gas constant = 0.08206 L atm #mol^-1##K^-1# )

V= 0.08206 L atm #mol^-1##K^-1# x 546 K / 1atm x 11.2 L

V= 44.80 L atm #mol^-1##K^-1# K / 11.2 L atm = 4.00 L
