Answer 2

The percentage concentration of the solution is 40.47%.

Given: 300 g rice grains and 540 ml water.

To find: We have to find the percentage concentration.

Solution:

Percentage concentration is a ratio of the mass of solute to the total mass of the solvent multiple by 100.

The mass of solute rice is equal to 300 grams.

The mass of the solvent is 540 ml.

This total mass of the solution is 540+300=840 ml.

Percentage concentration will be-

$\frac{340}{840} \times 100 = 40.47$

Thus the percentage concentration of the solution is 40.47%.
