Hello, There! Your Answer is Below

2.4 x 1024 ions

Explanation:

220 g of CaCl₂  =  X moles

Solving for X,

                                                X  =  (220 g × 1 mol) ÷ 110.98 g

                                                X  =  1.98 moles

As,

                          1 mole contained  =  1.20 × 10²⁴ Cl⁻ Ions

Then,

                   1.98 mole will contain  =  X Cl⁻ Ions

Solving for X,

                                                 X  =  (1.98 mol × 1.20 × 10²⁴ Ions) ÷ 1mol

                                                 X  =  2.38 × 10²⁴ Cl⁻ Ions

Hope this Helps!

Have a great DAy!

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
