Calcium chloride when
dissolved in water dissociates
into its ions according to
the following equation:
CaCi2(aq)Ca2+(aq)+2CH(aq)
Calculate the number of ions
obtained from CaCi2 when
1332 g of it is dissolved in
water.

Answer:
CaCl2(aq) ------→ Ca2+ + 2Cl-
1 mole of CaCl2. ---→ 3 × 6.022 × 10^23
1332/111 moles of CaCl2 → 1332/111×3×6.022×10^23
→2.2 × 10^25
Therefore,
1332g of CaCl2 will give 2.2 × 10^25 ions
