Answer 1

Answer #1

Balanced chemical reaction is

N₂ + 3H₂ $\rightarrow$ 2NH₃

molar mass of N₂ = 28.0134 g/mole

no.of mole = gm of compound / molar mass

mole of N₂ = 100 / 28.0134 = 3.5697 mole

According to reaction 1 mole of N₂ produce 2 mole of NH₃ molar retion of N₂ to NH₃ = 1:2

therefore 3.5697 mole of N₂ produce NH₃ = 3.5697 X 2 = 7.14 mole

NH₃ will produced = 7.14 mole
