The amount of chlorine in the sample will be calculated by subtracting the mass of phosphorus from the total mass of the compound.

mass of chlorine = (50.51 g) - (11.39 g)

= 39.12 g

The mass percent of phosphorus in the sample is,

% phosphorus = (11.39 g / 50.51g) x 100% = 22.55%

and that chlorine is,

% chlorine = (39.12 g/50.51 g) x 100% = 77.45%
