How many moles of phosphorus trichloride are in 200 grams of the molecule?

62.67 mol

27,466.6 mol

1.46 mol

0.69 mol

1.46 moles

Explanation:

We are given;

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
