Answer:
Mass = 15.13 g
Step-by-step explanation:
Given data:
Mass of ammonia formed = ?
Number of hydrogen atoms = 8.11× 10²³ atoms
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
1 mole = 6.022× 10²³ atoms
8.11× 10²³ atoms × 1 mol / 6.022× 10²³ atoms
1.35 moles of hydrogen
Now we will compare the moles of hydrogen and ammonia,
H₂ : NH₃
3 : 2
1.35 : 2/3×1.35 = 0.89
Mass of ammonia:
Mass = number of moles × molar mass
Mass = 0.89 mol × 17 g/mol
Mass = 15.13 g
