3. Choose a basis of 100g of mixture for the calculations. The, molar amount of each component is:
Methyl chloroformate: 50 g/(94.5 g/mol) = 0.529
Methyl chloride: 50 g/(50.5 g/mol) = 00.99 gmol
The number of gmol of each element is:
C: (0.529 gmol) (2) + (0.99 gmol) (1) = 2.05 gmol
H: (0.529 gmol) (3) + (0.99 gmol) (3) = 4.56 gmol
Cl: (0.529 gmol) (1) + (0.99 gmol) (1) = 1.52 gmol
O: (0.529 gmol) (2) = 1.06 gmol
Total: = 9.19 gmol
The ultimate analysis on a gmol basis (i.e., composition by gmol% of each element) is:
