Question

If the solubility of Copper Sulphate in 100g of water at 45°C is 29 g:a.Evaluateits solubility in 50 g of water at the same temperature.b.Calculate its concentration in terms of mass by mass percentage of the solution.

Answer 1

Answer:

Here ,Mass of solute (copper sulfate ) =110 g

And ,we know that :

Concentration of solution =Mass of solute Mass of solution ×100

=110550×100

=1005

=20per cent (or 20 % )

Thus , the concentration of this copper sulfate solution is 20 per cent (or it is 20% copper sulfate solution )
