In the reaction of 5.44 g of H2 with excess N2, a chemist isolates 7.56 g of NH3. what is the percent yield in the reaction?
3 H2 + N2 -----------------> 2 NH3
6.00 g 34 g
5.44 g ??
6 g H2 --------------> 34 g NH3
5.44 g H2 ---------------> ??
theoretical yield of NH3 = 5.44 x 34 / 6 = 30.83 g
actual yield = 7.56 g
percent yield = actual / theoretical ) x 100
= 7.56 / 30.8) x 100
percent yield = 24.5 %
