Answer:
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
