Ammonia (NH3) is widely used as a fertilizer and in many household cleaners. How much ammonia is produced when 5.81 mol of hydrogen gas react with an excess of nitrogen gas?

65.841 g

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
