where B(T) and C(T) are functions of temperature. For neon at 25°C, the values of B(T) and C(T) are 11.42 cm³.mol-1 and
221 cmé.mol2, respectively. Assuming the pressure calculated using the virial equation is the "true" value, determine the
percent error by using ideal gas law and van der Waals equation.
