Question

21.5 g of sodium chloride dissolves in 60g of water at 25oC. Calculate the solubility of sodium chloride at that temperature.

Answer 1

Here, mass of solute = 21.5g whereas mass of solvent is 60g.


Given, the temperature of solubility is 25 degree Celsius.


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

Solubility of the mixture = 21.5/60 x 25 = 8.96

Answer 2

HEY!!

____________________________

▶Solubility of a Solute = (Wt. of Solute in Sat. Soln. / Wt of Solvent in Sat. Soln.) X 100

✔(21.5/60) X 100

✔35.833 g/100 g of Water.

▶▶As water has density 1g/cc solubility is expressed as 35.833 g/100mL of water
