Question

Calculate Formula Unit mass for Zinc Oxide, Sodium Oxide, Sodium Chloride, Magnesium Carbonate, Copper Sulphate, Sodium Carbonate, Ammonium Hydroxide.

Answer 1

Dear Student,

Formula Unit mass for

Zinc Oxide, ZnO = 65 + 16 = 81g/mol

Sodium Oxide, Na₂O = 2(23) + 16= 62 g/mol

Sodium Chloride, NaCl = 23+35.5 = 58.5 g/mol

Magnesium Carbonate, Mg(CO₃)₂ = 24 + 2(12 +3×16) = 144 g/mol

Copper Sulphate, CuSO₄ = 64+ 32 + (4 × 16) = 160 g/mol

Sodium Carbonate, Na₂CO₃ = 2× 23 + 12 + 3 × 16 = 106 g/mol

Ammonium Hydroxide, NH₄OH = 14 +4 ×1+16+1 = 35 g/mol
