If 321.5 grams of phosphorus chloride are made, how many grams of phosphorus were consumed?
blagie [28]

If 321.5 grams of phosphorus chloride are made, then 168.235 grams of phosphorus were consumed.

<h3>What is the relation between mass & moles?</h3>

Relation between the mass and moles of any substance will be represented as:

  • n = W/M, where
  • W = given mass
  • M = molar mass

Moles of phosphorous chloride = 321.5g / 74.55g/mol = 4.315 mole

Given chemical reaction is:

2K + Cl₂ → 2KCl

From the stoichiometry of the reaction:

2 moles of KCl = produced by 2 moles of K

4.315 moles of KCl = produced by 4.315 moles of K

Mass of potassium = (4.315mol)(39g/mol) = 168.235 g

Hence required mass of phosphorous is 168.235 g.
