Question

A solution contains 40g of sugar dissolved in 200ml of water caluculate the concentration of this solution

Answer 1

Concentration = Weight of solute/ Volume of solvent x 100. So concentration here = 40/200 x 100= 20%

Answer 2

Answer: Mass of sugar (Solute) = 40gm

Mass of water (solvent) = 200 gm

Mass of solution = 40+200 = 240gm

Concentration = (Mass of Solute / Mass of Solution) * 100

Concentration = (40/240)*100 = 16.66%  

Concentration of solution is 16.66%.

Hope it helps you buddy...
