What is the mass of solute dissolved in 50,0 g of 12.5% saline solution? A) 7.148 B) 6.258 C) 43.88 D) 4.00 g
Marizza181 [45]

Answer:

6.25 grams is the mass of solute dissolved.

Explanation:

w/w % : The percentage mass or fraction of mass of the of solute present in total mass of the solution.

w/w\%=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100

Mass of the solution = 50.0 g

Mass of the solvent = x

w/w % = 12.5%

12.5\%=\frac{x}{50.0 g}\times 100

x = 6.25 g

6.25 grams is the mass of solute dissolved.
