The solubility of silver chloride is 1.562 × 10-10 mol dm-3 at 298 K.

1.	The solubility of silver chloride is 1.562 × 10-10 mol dm-3 at 298 K. Find its solubility in g dm-3 at the same temperature.
Answer» Given : Solubility of AgCl = S = 1.562 × 10^-10 mol dm^-3 Solubility of AgCl in g dm^-3 = ? Molar mass of AgCl = M = 143.5 g mol^-1 Solubility in gram per dm³, = solubility in mol dm^-3 × molar mass = 1.562 × 10^-10 × 143.5 = 2.241 × 10^-5 g dm^-3 ∴ Solubility of AgCl = 2.241 × 10^-8 g dm^-3

The solubility of silver chloride is 1.562 × 10-10 mol dm-3 at 298 K. Find its solubility in g dm-3 at the same temperature.

Answer»

Given :

Solubility of AgCl = S = 1.562 × 10^-10 mol dm^-3

Solubility of AgCl in g dm^-3 = ?

Molar mass of AgCl = M = 143.5 g mol^-1

Solubility in gram per dm³,

= solubility in mol dm^-3 × molar mass

= 1.562 × 10^-10 × 143.5

= 2.241 × 10^-5 g dm^-3

∴ Solubility of AgCl = 2.241 × 10^-8 g dm^-3
