Question

4. What is the concentration (in percentage by mass) of a solution that contains 50g of sugar in 500g of solution?

Answer 1

Explanation:

concentration = mass of solute/mass of solution

=(50/50+500)×100

=(50/55)×10

=(100/11)

=9.09090909091

hope it helps you

Answer 2

The concentration of the solution in percentage by mass is 10%.

Given: A solution contains 50g of sugar in 500g of solution.

To find: We have to find the concentration of the solution.

Solution:

The concentration of a solution in percentage by mass is the ratio of the mass of solute to the total mass of the solution multiple by 100.

Mass of solute sugar is equal to 50 grams.

The mass of the solution is 500 grams.

So, concentration will be-

$\frac{50}{500} \times 100 = 10\%$

Thus the concentration of the solution in percentage by mass is 10%.
