Calculate the percentage concentration of the remaining solution when 500 g of a `20%` solution by weight is cooled, 40 g of solute is precipitated.

Text Solution

Verified by Experts

Weight of solution `=500g`
Weight of solute`=(20xx500)/(100)=100g`
Weight of solute precipitated`=40g`
Weight of solute left in the solution`=100-40=60g`
Weight of solution left`=500-40=460g`
