For the reaction: 2 P + 3 Cl₂ $\rightarrow$ 2 PCl₃,if 32.5 g of Cl₂ reacts completely with excess P, how many grams of PCl₃ will be produced?

Question

Quizplus · Accepted Answer

The balanced equation shows that 3 moles of Cl2 react with 2 moles of P. The molar mass of Cl2 is 70.9 g/mol, so 32.5 g of Cl2 is 0.458 mol. This will react with 0.305 mol of P, which has a molar mass of 30.97 g/mol. The mass of PCl3 produced will be 0.305 mol * 137.33 g/mol = 42.0 g.
