A substance that is not an ideal gas has an equation of state given by: pV²=nBT² , where p is the pressure in Pascals, V is the volume in m³, n is the number of moles, T is the temperature in kelvins, and B is a constant equal to B =0.0932 N•(m²)²/(mol•K²) . If 3.43 moles of this gas undergoes isothermal expansion at T = 216K from a volume of 1.00 m³ to 3.00 m³, calculate the work done by the gas.
