Answer:
28g
Explanation:
Given parameters:
Number of moles of hydrogen = 3moles
Unknown:
Mass of nitrogen used = ?
Solution:
To solve this problem, let us establish the balanced reaction equation first;
N₂ + 3H₂ → 2NH₃
From the balanced reaction equation;
3 mole of H₂ will combine with 1 mole of N₂
Now,
Mass of Nitrogen = number of moles x molar mass
Molar mass of N₂ = 2(14) = 28g/mol
Mass of Nitrogen = 1 mole x 28g/mole = 28g
