!PLEASE HELP ASAP! Ammonium chloride reacts with calcium oxide to produce ammonia, calcium chloride, and water. If 7.4 grams of ammonia are produced, how many grams of calcium chloride are also
produced?

Mass of calcium chloride produced = 24.14 g

Explanation:

Given data:

Mass of ammonia produced = 7.4 g

Mass of calcium chloride produced = ?

Solution:

Chemical equation:

2NH₄Cl + CaO      →   2NH₃ + H₂O + CaCl₂

Number of moles of ammonia produced:

Number of moles = mass/molar mass

Number of moles = 7.4 g/ 17 g/mol

Number of moles =  0.435 mol

Now we will compare the moles of ammonia and calcium chloride.

             NH₃          :         CaCl₂

              2              :              1

          0.435          :         1/2×0.435 = 0.2175 mol

Mass of calcium chloride produced:

Mass = number of moles × molar mass

Mass = 0.2175 mol ×110.98 g/mol

Mass = 24.14 g
