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

What was the resulting molarity of your primary standard solution of potassium iodate kio3?
melamori03 [73]
Missing question: 0,535 gram of KIO₃ dissolved in 250 mL of de-ionized water to <span>make primary standard solution.
m(</span>KIO₃) = 0,535 g.
V(KIO₃) = 250 mL ÷ 1000 mL/L = 0,25 L.
n(KIO₃) = m(KIO₃) ÷ M(KIO₃).
n(KIO₃) = 0,535 g ÷ 214 g/mol.
n(KIO₃) = 0,0025 mol.
c(KIO₃) = n(KIO₃) ÷ V(KIO₃).
c(KIO₃) = 0,0025 mol ÷ 0,25 L.
c(KIO₃) = 0,01 mol/L = 0,01 M.
