You can practice converting between the mass of a solution and mass of solute when the mass percent concentration of a solution
Ostrovityanka [42]

Answer:

145 grams of a 0.480 % KCN solution contains 697 mg of KCN.

Explanation:

w/w % : The percentage mass or fraction is mass of the of solute present in 100 grams of the solution.

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

given =  w/w% = 0.480 %

Mass of solute that KCN = 697 mg = 0.697 g

(1 mg = 0.001 g)

Mass of the solution = ? = x

0.480\%=\frac{0.697 g}{x}\times 100

x=\frac{0.697 g}{0.480}\times 100

x = 145.21 g ≈ 145 g

145 grams of a 0.480 % KCN solution contains 697 mg of KCN.
