Question

For the reaction: 2X + 3Y r 3Z, the combination of 2.00 moles of X with 2.00 moles of Y produces 1.75 moles of Z. What is the percent yield of this reaction?

Do you make up some numbers?

Answer 1

2 X + 3 Y --> 3 Z
X is limiting
2 moles of X should yield 3 moles of Z
You obtained 1.75 moles of Z
1.75 / 3.00 = 0.583 (58%) this might help..
