solubility of salt at 40℃ is 40.find the mass residue left when 100g of saturated solution is heated.
Answers
The mass of residue left is 60 g
Explanation:
A solution consists of solute and solvent.
A solute is defined as a component that is present in a smaller proportion while a solvent is defined as a component that is present in a larger proportion.
A saturated solution is defined as the solution when no more solute can be dissolved in the solution
An unsaturated solution is defined as the solution when more of the solute can be dissolved in the solution.
Solubility is defined as the amount of solute present in 100 g of solvent to make a saturated solution.
We are given:
Solubility of salt = 40 g
This means that 40 g of solute is present in 100 g of solvent
Mass of saturated solution = 100 g
Amount of residue left = [100 - 40] g = 60 g
Hence, the mass of residue left is 60 g
