Question

solution contains 60 gram of common salt in 450 water calculate the concentration in terms by mass percentage of the solution

Answer 1

Explanation:

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%)
