let's understand the molarity of solution
the molarity is defined as
number of mole of solute / volume of solvent ( in Liter)
So,
0.20 M means
0.2 Mole of CaCl2 in 1000 ml of water
or
1000ml of the solution have 0.2 Mole of CaCl2
250 ml of the solution have (0.2 *250) /1000 Mole of CaCl2 = 0.05 Mole of CaCl2
