Question

a solution contains 30 gram of sugar dissolves in 270 gram of water calculate the concentration of in terms in terms of mass by mass percentage of the solution​

Answer 1

$\huge\mathrm{\pink{Answer}}$

A Solution contains 30 g of sugar dissolved in 370 g of water, Calculate the concentration of this solution . THus , the concentration of this sugar solution is 7.5 per cent (or that it is a 7.5 % sugar solution).

Answer 2

We know that concentration of solution= Mass of Solute/Massof solution x 100

Here, Mass of solute (sugar) = 30 g and ,

Mass of Solvent (water) = 370 g So,

Mass of solution = Mass of solute + Mass of solvent = 30 + 370 = 400g Now,

putting the values of ‘mass of solute’ and ‘mass of solution’

in the above formula,

we get: Concentration of solution =30/400 x 100=30/4=7.5 percent (or 75%)
