Expert Solution
Introduction:

Ideal gas law states that the product of volume (L) and pressure (atm) is equal to the product of moles (mol), temperature (K) and gas constant (0.0821 L atm K-1 mol-1). The ideal gases have no interactions among themselves (i.e. no interaction and no repulsion). Real gases are those which are opposite of that of ideal gases (i.e. ideal gas law is not followed by them). The mathematical expression of ideal gas law is:

PV = nRT

Where;

P = Pressure

V = Volume

n = Moles

R = Gas constant

T = Temperature

Given data:

n = 0.500 mol

R = 0.0821 L atm K-1 mol-1

T=25°C=25+273=298 K

V=500 mL=5001000=0.500 L
