Calculate molarity of one litre solution of 22.2 gm CaCl ₂ .

Step-by-step solution

aligned & Molarity (M) & = mass of solute (in g ) molecular weight of solute = 222 ~g 111 ~g ~mol ⁻¹ 1 ~L & Volume of solution (in L ) & [ Molecular weight of CaCl ₂=111 ~g ~mol ⁻¹ ] & =0.2 ~mol ~L ⁻¹=0.2 M . aligned
