Question

How many moles of hydrogen, H2, are needed to react with 175 moles of nitrogen gas in the reaction forming ammonia?

Answer 1

525 moles `H_2`

Explanation:

`3H_2 + N_2 = 3 NH_3`

for every mole of `N_2`, you need 3 moles of `H_2`

175moles `N_2` * `(3 mol H_2)/(1 mol N_2)` = 525 moles `H_2`
