Question

a solution is prepared by adding 40 g of sugar in 100ml of water . calculate the concentration

Answer 1

Volume of water = 100ml

Mass of sugar = 40g

We know that volume will not change because the particles of sugar will adjust themselves in the intermolecular space of water.


So volume of solution = volume of solvent = 100ml

We know that,

concentration
= mass of solute/volume of solution × 100

=> 40/100 × 100

= 40%


Hence, the concentration is 40%

Hope it helps dear friend ☺️✌️
