How many chloride ions are there in 4 mol of CaCl2

48.176 ×10²³ chloride ions

Explanation:

Given data:

Number of chloride ions = ?

Number of moles of CaCl₂= 4 mol

Solution:

One mole of CaCl₂ contain 2 moles of chloride ions.

CaCl₂      →     Ca²⁺ + 2Cl⁻

4 moles of CaCl₂ contain,

4 ×2 = 8 moles of chloride ions

Number of chloride ions:

1 mole = 6.022×10²³ ions

8 mol × 6.022×10²³ ions/ 1 mol

48.176 ×10²³ ions

56 moles of   lieter in chemistry
