Question

Given this equation: N2 + 3 H2 → 2 NH3, how many moles of NH3 can be produced from 7.4 moles of H2?

Answer 1

4.93 moles of NH₃ will be produced from 7.4 moles of H₂

To solve this problem, let's us the equation of reaction.

From the stoichiometry of the reaction,

3 moles of H₂ produce 2 moles of NH₃

let's make the unknown moles of NH₃ = x

3 mole of H₂ = 2 moles of NH₃

7.4 mole of H₂ = x moles of NH₃

we can proceed to cross multiply both sides and solve for x

$\begin{gathered} x=\frac{7.4\times2}{3} \\ x=4.93 \end{gathered}$

From our calculations above, 4.93 moles of NH₃ will be produced from 7.4 moles of H₂
