Question
A vessel contains at 1 bar and 20°C a mixture of 1 mole of CO2 and 4 moles of air. Calculate
for the mixture:
(i) The masses of CO2, Oz and N2;
(ii) The percentage carbon content by mass;
(iii) The apparent molecular weight and the gas constant for the mixture;
(iv) The specific volume of the mixture;
(v) If the mixture is heated at constant pressure to 100°C, find the changes in internal
energy, enthalpy and entropy of the mixture.
