Answer
113.1 g PCl5
Work Step by Step
Theoretical yield:
Find the moles of PCl3 from the grams of PCl3 by dividing by its atomic mass.
92.5g/ 137.32g/mol = 0.71 mol PCl3
Find the moles of PCl5 produced from the PCl3 by multiplying by the molar ratio.
0.71 mol PCl3 x (1 mol PCl5/1 mol PCl3) = 0.71 mol PCl5
Find the number of grams of PCl5 by multiplying the moles of PCl5 by the molar mass.
0.71 mol PCl5 x 208.22g/mol = 147.84 g PCl5
Actual yield = Theoretical Yield x (Percent yield/100)
= 147.84 g x 0.765 = 113.1 g PCl5
