Question

23. To make a saturated
solution 48g of copper
sulphate is dissolved in 100g
Of water at 283K. Find its
concentration at this
temerature ​

Answer 1

Answer:

Mass of solute (coppersulphate) = 48 g

           Mass of solvent (water) = 100 g

           Mass of solution

           = Mass of solute + Mass of solvent

           = 48g + 100 g = 148g

Concentration = (Mass of Solute / Mass of Solution) * 100

Concentration = (48/148)*100 = 32.43%

If temperature increases solubility increases and if temperature decreases than solubility will also decreases.
