Answer: -

37.5 g of NaCl are in 250 g of a 15.0% (by weight) solution.

Explanation: -

Total mass = 250 g

Percentage of NaCl = 15.0 %

=
(Number of grams of NaCl present)/(total mass)

Thus
(15)/(100) =
(Number of grams of NaCl present)/(250g)

Number of grams of NaCl present =
(15 x 250g)/(100)

= 37.5 g
