Solubility of sodium chloride was 36 g at 20.d egree. C.100 g of sodium chloride solid was added to 200 g of water at 20.d egree. C Stir and filtering to obtain that mass of solute in the obtained solution Score Solubility of sodium chloride was 36 g at 20.d egree. C.100 g of sodium chloride solid was added to 200 g of water at 20.d egree. C Stir and filtering to obtain that mass of solute in the obtain solution Score
Solubility is equal to the mass of solute saturated in 100 g of "water ".
That is,100 g of water dissolves up to 36 g of sodium chloride
200G water dissolution 72g
Then solution mass =200+72 g =272 g
The mass fraction is 72g/272g
(Mass fraction refers to the mass of the solute compared to the mass of the "solution ")
