Answer:
166.56g of NH3 are produced
Explanation:
The reaction of N2 with H2 to produce NH3 is:
N2 + 3H2 → 2NH3
<em>Where 1 mole of N2 produce 2 moles of NH3</em>
<em />
4.89 moles of N2 with excess of H2 produce:
4.89 moles N2 * (2 moles NH3 / 1 mole N2) = 9.78 moles NH3
As molar mass of NH3 is 17.031g/mol, mass of NH3 produced is:
9.78 moles * (17.031g / mol) =
<h3>166.56g of NH3 are produced</h3>
