To calculate the percent yield, we need to determine the theoretical yield of sodium nitrate (NaNO3) and then compare it to the actual yield given in the problem.Given information:- Reaction:
- 50.0 grams of ammonium nitrate (NH4NO3)- 60.0 grams of sodium phosphate (Na3PO4)- Actual yield of NaNO3: 0.611 molStep 1: Calculate the molar mass of sodium nitrate (NaNO3).Molar mass of NaNO3 = 22.99 g/mol (Na) + 14.01 g/mol (N) + 16.00 g/mol (O) = 85.00 g/molStep 2: Calculate the theoretical yield of sodium nitrate (NaNO3).Theoretical yield of NaNO3 = (0.611 mol) × (85.00 g/mol) = 52.135 gStep 3: Calculate the percent yield.Percent yield = (Actual yield / Theoretical yield) × 100%Percent yield = (0.611 mol × 85.00 g/mol) / 52.135 g × 100% = 97.8%Therefore, the correct answer is
