PLEASE HELP ME ASAP

N2 + 3H2 → 2NH3
How many grams of ammonia,
NH3, would be formed from the
complete reaction of 4.50 moles
hydrogen, H2?

Answer 1

Mass = 51 g

Step-by-step explanation:

Given data:

Mass of ammonia formed = ?

Number of moles of hydrogen = 4.50 mol

Solution:

Chemical equation:

N₂ + 3H₂ → 2NH₃

Now we will compare the moles of hydrogen and ammonia.

H₂ : NH₃

3 : 2

4.50 : 2/3×4.50 = 3 mol

Mass of ammonia formed:

Mass = number of moles × molar mass

Mass = 3 mol × 17 g/mol

Mass = 51 g
