<h3>Answer:</h3>

1.46 moles

<h3>Explanation:</h3>

<u>We are given</u> ;

  • Mass of  phosphorus trichloride is 200 g

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

  • We know that to calculate the number of moles we divide mass by the molar mass.
  • That is;

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
