Question

Using the equation

N2+3H2-->2NH3

how many grams of NH3 is made if 11 grams of N2 are used?

Answer 1

13.36

first you have to convert the grams of nitrogen into moles when you got the moles of nitrogen. Then 2 moles of ammonia react with 1 mole nitrogen you have doubled the nitrogen mole and then convert the moles into the grams of ammonia.

use this formula for that:

moles = gram/molar mass
