Answer 1

Answer:

mole of calcium chloride = 111g

Therefore,

222g of CaCl2 is equivalent to 2 moles of CaCl2

Since 1 formula unit CaCl2 gives 3 ions,

therefore,

1 mol of CaCl2 will give 3 moles of ions 2 moles of CaCl2 would give 3×2=6 moles of ions.

No. of ions = No. of moles of ions × Avogadro number

= 6 × 6.022 ×1023

= 36.132×1023

= 3.6132 × 1024 ions
