Question

No of chloride ions present in 0.1 mole calcium chloride is

Answer 1

no or number of Cl ions.

Answer 2

Answer:

No chloride ions present in 0.1-mole calcium chloride is 1.81 × $10^2^0$ ions

Explanation:

MOLALITY:

Molality is likewise referred to as molal concentration. It is a degree of solute concentration in a solution. The answer consists of components; solute and solvent. There are many special approaches to specify the concentration of answers like molarity, molality, normality, formality, extent percentage, weight percentage, and element according to million. The time period desires to calculate the mass of the solvent and moles of solute.

calculation:

0.1M solution means that you have 0.1 mol of $CaCl_2$ in 1000mL answer

But  $CaCl_2$ solution  = 3 ions / molecule

Therefore,

The 0.1M  $CaCl_2$ solution = 0.3M in respect of ions.

You have 0. 3 mol ions in 1000 mL solution

You have 0.3/1000 = 0.0003 mol ions in 1 mL solution

A number of ions:

1 mol of ions = 6.022 ×$10^2^3$ ions

0.0003 mol ions = (0.0003) × (6.022 × $10^2^3$ ) = 1.81 × $10^2^0$ ions
