Question

If 2.27 moles of bromine react with excess phosphorus, how many moles of phosphorus tribromide will be produced

Answer 1

Answer:

The answer to your question is 1.51 moles of PBr₃

Explanation:

Data

moles of Br = 2.27

moles of PBr₃ = x

Balanced chemical reaction

                   2P   +   3Br₂  ⇒   2PBr₃

             Reactant      Element     Products

                   2                  P                 2

                   6                  Br                6

-Use proportions to find the answer

              3 moles of Br₂ ------------------  2 moles of PBr₃

         2.27 moles of Br₂ ------------------  x

               x = (2.27 x 2) / 3

               x = 4.54 / 3

              x = 1.51 moles
