Question

24g salt is dissolved in 300 g solution. Calculate the concentration in terms of mass by mass percentage of the solution.​

Answer 1

Answer:

mass of solute× mass of solution×100

24÷300×100

=8g

Answer 2

Explanation:

% w/w = mass of solute÷mass of solution×100

=24÷300×100

=8g

2) same equation as above.

10 = 40÷ mass of solution × 100

=400g is the mass of solution.

therefore, 400= mass of solvent + 40

mass of solvent = 360g
