Question

Calculate the amount of water required to prepare 500 gram of 2.5 solution of sugar​

Answer 1

Answer:

Explanation:

Mass percent = mass of solute / mass of solution .

Where mass of solution = mass of solute +  mass of solvent

Here mass of solution = 500g

Mass percent = 2.5 % 

Let the mass of solute be x.

Then 2.5 %  = x / 500

⇒ x = 12.5g

Hence mass of sugar is 12.5 g

∴ mass of solvent = mass of solution - mass of solute

∴ mass of solvent = 500 g - 12.5g

⇒ mass of solvent = 487.5 g 

Hence 487.5 g of water is required to prepare 500g of 2.5 % sugar solution.
