Question

What is the percent yield if 108.40 g O2 reacts with excess NH3 according to the balanced equation below and the actual yield is found to be 203.50 grams of H2O?

4 NH3 + 5 O2 → 4 NO + 6 H2O

Answer 1

To express the efficiency of a reaction, you can calculate the percent yield using this formula: %yield = (actual yield/theoretical yield) x 100. A percent yield of 90% means the reaction was 90% efficient, and 10% of the materials were wasted (they failed to react, or their products were not captured).
