Question

Calculate the percent yield if 500 grams of C7H8 makes 255 grams of C7H7NO2

Answer 1

I’m still thinking about it

Answer 2

500/92 = 5.43 mol of C7H8
1:1 mol ratio
Mass = mol x Mr = 5.43 x 137 = 743 g (theoretical yield)
Percentage yield = ( actual yield / theoretical yield ) x 100
500/743 x 100 = 67.3% 1dp
