Question

How many NH3 molecules are produced by the reaction of

4.0 mol of Ca(OH)2 according to the following equation:
(NH4)2SO4 + Ca(OH)2 → 2 NH3 + CaSO4 + 2 H₂O

Answer 1

1 mol Ca(OH)2 produces 2 mol NH3

4 mol Ca(OH)2 will produce 8 mol NH3

1 mol NH3 contains 6.022*10^23 molecules NH3

8 mol NH3 contain 8*6.022*10^23 = 4.8*10^24 molecules NH3
