Question

21 g of sodium chloride dissolves in 60 g of water at 20° C to form a saturated solution. What is the solubility of sodium chloride at 20° C? ​

Answer 1

Answer:

Hence, solubility of the sodium chloride at 20° C is 8.75

Explanation:

Here, mass of solute = 21 g whereas mass of solvent is 60 g.

Given, the temperature of solubility is 20 degree Celsius.

Since, Mass of solute/ mass of solvent x temperature = solubility of the mixture

Solubility of the mixture = 21/60 x 25 = 525 / 60 = 8.75

Hence, solubility of the sodium chloride at 20° C is 8.75
