Question

A solution made by dissolving 25g of glucose in 250g of water. Calculate the concentration of this solution in mass percentage.

Answer 1

Given:-

→Mass of Glucose (Solute) = 25g

→Mass of water (Solvent) = 250g

To find:-

→Concentration of the solution in terms of mass by mass percentage.

Solution:-

Here, mass of solute and mass of solvent are given. So firstly, let's calculate the total mass of the solution. It can be calculated as follows:-

Mass of solution:-

= Mass of Solute + Mass of Solvent

= (250+25) g

= 275g

Hence,we have got mass of the solution

as 275g. Now let's calculate the concentration of the solution.

Concentration of a solution:-

= Mass of solute/Mass of solution×100

= 25/275×100

= 2500/275

= 9.09%. (approximately)

Thus,concentration of the solution in terms of mass by mass percentage is 9.09%.
