0.1M solution means that you have 0.1 mol of CaCl2 in 1000mL solution
But CaCl2 ↔ C+ 2+ + 2Cl- = 3 ions / molecule
Therefore the 0.1M CaCl2 solution = 0.3M in respect of ions.
You have 0.3 mol ions in 1000 mL solution
You have 0.3/1000 = 0.0.0003 mol ions in 1 mL solution
Number of ions:
1 mol of ions = 6.022*10^23 ions
0.0003 mol ions = (0.0003)*(6.022*10^23) = 1.81*10^20 ions.
