For the reaction represented by the equation SO3 + H2O → H2SO4, calculate the percentage yield if 500. g of sulfur trioxide is produced and the theortical yield is 575 g of sulfur trioxide.

Select one:
a. 86.9 %
b. 85.2 %
c. 89.3 %
d. 88.1 %

I did the math and received 93.9%, which is not an answer choice. Can someone steer me in the right direction?

Answer 1

I would make 500 grams of SO3 into moles, as well as 575 grams.

Note that the molecular mass of SO3=roughly 80 grams

Answer 2

Would the answer be A.)?

This question is really tricky for me!

Answer 3

yeah, i'm getting A as well

Answer 4

Thanks again!

Answer 5
