Question

For the following reaction, 6.33 grams of hydrogen gas are mixed with excess nitrogen gas. The reaction yields 25.7 grams of ammonia.


N2 (g) + 3 H2 (g) = 2 NH3 (g)





(1) What is the theoretical yield of ammonia ?

grams



(2) What is the percent yield for this reaction ?

%

Answer 1

It's not computer science.

Answer 2

You might want to try the Chemistry group instead. :)

Remeber that chemistry equations are just like normal equations. Let x, y, z be the quantity of hydrogen, nitrogen and ammonia, then the equation becomes:

N2 (g) + 3 H2 (g) = 2 NH3 (g)
2y + 6x = 2z
