The vapour pressure of a pure substance at a temperature 
is 30 bar . The actual and ideal gas values of 
for the saturated vapour at this temperature and 30 bar are 7.0 and 7.7, respectively. Here, 
is the molar Gibbs free energy and 
is the universal gas constant.
The fugacity of the saturated liquid at these conditions, rounded to 1 decimal place, is 
bar.
