Question

The concentration of a 250 g of sugar solution is 7.5%
(w/w). The total amount of sugar present in this solution
is​

Answer 1

total amount of sugar is 18.75

Answer 2

Answer:

The total amount of sugar present in this solution is 18.75g.

Explanation:

The weight by weight (w/w) percentage of the solution is given as,

$w/w=\frac{M_s}{M_S} \times 100$               (1)

Where,

Ms=mass of the solute

MS=mass of the solution

From the question we have,

MS=250g

w/w=7.5

By substituting the required values in equation (1) we get;

$7.5=\frac{M_s}{250} \times 100$

$M_s=\frac{7.5\times 250}{100} =18.75g$

Hence, the total amount of sugar present in this solution is 18.75g.
