How many moles of phosphorus trichloride are in 200 grams of the
62.67 mol
27,466.6 mol
1.46 mol
0.69 mol

1.46 moles

We are given ;

We are required to calculate the number of moles of phosphorus trichloride;

Moles = Mass ÷ Molar mass

Molar mass of phosphorus trichloride = 137.33 g/mol

Therefore;

Moles = 200 g ÷ 137.33 g/mol

           = 1.456 moles

           = 1.46 moles

Therefore, the moles of phosphorus trichloride are 1.46 moles
