Question

The reaction between NH3 and O₂ produces 21.8 g of NO gas and some water. Determine the percent yield if the theoretical yield is 27.9 g of NO

gas. Please show your work on a scrap piece of paper.
128.0%
78.1 %
1.28 %
0.78%

Answer 1

To find percent yield - actual/theoretical

So do 21.8g/27.9g = 0.78

Multiply by 100 to get a percent

0.78 x 100 = 78.1%
