782g
Explanation:
Given parameters:
Number of moles of N₂ = 23moles
Unknown:
Mass of NH₃ = ?
Solution:
We first obtain the balanced chemical equation for this reaction;
N₂ + 3H₂ → 2NH₃
From the equation we see that;
1 mole of N₂ produced 2 moles of ammonia
23 mole of N₂ will yield 2 x 23 = 46moles of ammonia
Now ;
mass of ammonia = number of moles x molar mass
Molar mass of NH₃ = 14 + 3(1) = 17g/mol
Mass of ammonia = 46 x 17 = 782g
