Question

В 60 г раствора содержится 18 г соли. Определите массовую долю соли в данном растворе

Answer 1

Дано:
m(р-ра) =60г
m(рв) =18г.
Рещение:
W(рв) =m(рв) /mр-ра) *100%
W(рв) =18/60*100%=30%
Ответ: W(рв) =30%

Answer 2

Calculating the Mass Fraction of Salt in a Solution

To determine the mass fraction of salt in the given solution, we can use the formula:

Mass fraction = (mass of salt / total mass of solution) x 100%

Given that the solution contains 18 g of salt in a 60 g solution, we can calculate the mass fraction of salt.

Using the formula: Mass fraction = (18 g / 60 g) x 100%

Calculation

The mass fraction of salt in the given solution is: Mass fraction = (18 g / 60 g) x 100% = 30%

So, the mass fraction of salt in the given solution is 30%.
