Answer:
65.841 g
Step-by-step explanation:
The balanced equation for this reaction is;
N2 + 3H2 → 2NH3
From the question, we are interested in ammonia and the hydrogen gas.
From the equation
3 mol of H2 produces 2 mol of NH3
5.81 mol would produce x
Solving of x;
x = 5.81 * 2 / 3
x = 3.873 mol
Converting to mass;
Mass = Number of moles * molar mass
Mass = 3.873 * 17 = 65.841 g
