Answer 2

The answer to your question is 1.51 moles of PBr₃

Step-by-step 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
