Question

The balanced chemical equation is P(s) + 6 Cl₂(g) →→ 4 PCl₂(g). What is the mass in grams of phosphorus trichloride that can be formed from 216.8 grams of chlorine gas based on the balanced chemical equation?​

Answer 1

279.895 grams

Step-by-step explanation:

216.8 / molar mass of Cl2 (71 grams) = 3.0535

3.0535 / 6 moles of Cl2 = 0.5089

0.5089 x 4 moles of PCl3 = 2.0356

2.0356 x molar mass of PCl3 (137.5 grams) = 279.895 grams of PCl3
