Question

10 g glucose is dissolved in 400g of solution. Calculate percentage concentration of the solution.

Answer 1

ans= 10g/400g × 100= 2.5%

Answer 2

10g glucose is dissolved in 400g of solution then the percentage for the concentration of solution is 2.5% by wt.

Step by step explanation:

Given: Weight of the solute is 10 g

Weight of the solvent is 400g

To find: Percentage for the concentration of the solution.

Formula used:    $Percentage concentration = \frac{Weight of solute}{Weight of solution}$  × 100

Solution:

The percentage of concentration  can be calculated by dividing the weight of the solute by the weight of the solvent and multiplying by 100.

$Percentage concentration = \frac{Weight of solute}{Weight of solution}$  × 100

Therefore 10 g of glucose is present in 400g of solution.

Weight of solute = 10

Weight of solvent = 400

$Perventage concentration = \frac{10}{400}$ × 100

$Percentage concentration = \frac{10}{4}$

Percentage concentration = 2.5 %

Final answer:

The percentage of concentration of a solution is 2.5 % by wt.
