Question

A solution contain 50g of sugar in 350g of water calculate the concentration of solution?

Answer 1

mass of solute = 50g
mass of solvent = 350g
mass of solution = 50 + 350 = 400g
mass by mass% = mass of solute / mass of solution
mass by mass = 50/400 * 100
= 100/8
 = 12.5%
mass by mass % = 12.5% 

Answer 2

Given:

• The mass of solute = 50 g
• The mass of solvent = 350 g

To Find:

• The concentration of the solution.

Solution:

The mass of solution = mass of solute + mass of solvent

The mass of solution = 50+350 = 400 g

The concentration of the solution is given by,

⇒ Concentration = mass of solute/mass of solution × 100

On substituting the values in above formula we get,

⇒ Concentration = (50/400)×100 {dividing the terms in bracket}

⇒ Concentration = 100/8 = 12.5% {dividing the terms}

∴ The concentration of the solution = 12.5%
