Question

У 226 г води розчинили 34 г солі. Розрахувати масову частку солі в розчині.

Answer 1

Ответ:масова частка солі в речовині 13%

Объяснение:

дано:

м(р.р)=34г

м(води) 226г

w(р.р.)-?

розв"язання:

м(р-ку)=226+34=260г

w(р.р.) м(р.р)\м(р-ну)*100%

w(р.р.)=34:260*100%=13%

Answer 2

Calculation of Mass Fraction of Salt in Solution

To calculate the mass fraction of salt in the solution, we need to know the masses of both the solvent and the solute.

Given: - Mass of water = 226 g - Mass of salt = 34 g

To calculate the mass fraction of salt in the solution, we use the formula:

Mass Fraction of Salt = (Mass of Salt) / (Mass of Solution)

The mass of the solution is the sum of the mass of water and the mass of salt:

Mass of Solution = Mass of Water + Mass of Salt

Let's calculate the mass fraction of salt in the solution:

Mass of Solution = 226 g + 34 g = 260 g

Mass Fraction of Salt = (34 g) / (260 g) = 0.1308

Therefore, the mass fraction of salt in the solution is approximately 0.1308 or 13.08%.

Please note that the above calculation assumes that the volume of the solution remains constant during the dissolution process.
