Question

Q11. 310 grams of solution
contains 8 grams of sugar. The
percentage amount of sugar in
the solution will be
1.96 %
2.58%
4%
3.22%​

Answer 1

Answer:

A solution contains a solid solute (sugar ) dissolved in a liquid solvent (water),so we have to calculate the concentration of this solution in terms of the mass percentage of solute (sugar ) we, Know that :

Concentration of solution =Mass of soluteMass of solution ×100

here, Mass of solute (sugar )=30g

And ,Mass of solvent (water)=370g

So ,Mass of solution = Mass of solute + Mass of solvent

=30+370

=400 g

Now ,Putting the values Of mass of solute and mass of solution in the above formula formula ,WE get :

Concentration of solution =30400×100

=304

7.5 per cent (or 7.5% )

THus , the concentration of this sugar solution is 7.5 per cent (or that it is a 7.5 % sugar solution).
