Can some me do this we have a final tomorrow and i have now idea how to do it. step by step explanation and tips if you know any

87.27 grams

Explanation:

The mole ratio of nitrogen to hydrogen is 1:3; while that one of hydrogen to the products (ammonia) is 3:2

Thus if 3 moles of hydrogen gas produce 2 moles of ammonia gas

7.7 moles of hydrogen will produce:

(7.7moles×2)/3

77/15 moles

1 mole of ammonia gas has a mass of  14+3=17

since the mass of an atom of nitrogen is 14 while that of hydrogen atom is 1.

Therefore 77/15 moles will have a mass of

77/15 moles × 17=87.27 grams
