Explanation / Answer

N2 + 3H2 ---> 2 NH3

no of mol of H2 reacted = w/mwt = 1.72/2 = 0.86 mol

no of mol of N2 reacted = 10/17 = 0.6 mol

limiting reactant = H2

noof mol of NH3 formed = 0.86*2/3 = 0.573 mol

theoretical yield of NH3 = 0.573*17 = 9.74 g

practical yield of NH3 = 1.22 g

percent yield = practical yield/theoretical yield*100

       = 1.22/9.74*100

       = 12.52%
