phosphorus pentachloride: PCl5
molar mass P = 30.974 g/mol
molar mass Cl = 35.45 g/mol
molar mass PCl5 = (30.974 g/mol x 1) + (35.45 g/mol x 5)
molar mass PCl5 = 208.224 g/mol
Mass percent of P:
total mass P = 30.974 g/mol x 1
total mass P = 30.974 g/mol
%P = 14.88%
Calculate the mass percent composition of each constituent element of phosphorus pentachloride.
