SUMMARY
The calculation of the mass of air in mass balance problems involves using the ideal gas law and understanding the composition of air, specifically the mass percentages of oxygen (21%) and nitrogen (79%). To convert these percentages into mass, one must apply the molar weights of oxygen (32 g/mol) and nitrogen (28 g/mol). This method is applicable for both continuous flow and batch processes, ensuring accurate mass flow descriptions.
