Question

к 260 г 5% раствора соли добавили 15 грамм соли . Вычислить массовую долю соли в полученном растворе

Answer 1

Находим массу соли в исходном растворе: 260*0.05=13г
массовая доля соли в полученном растворе : 13+15/260+15=0.10(10%)

Answer 2

Calculation of Mass Fraction of Salt in the Solution

To calculate the mass fraction of salt in the solution, we need to know the initial mass of the solution and the mass of the added salt.

Given: - Initial mass of the solution (260 g) - Mass of the added salt (15 g)

To find the mass fraction of salt, we can use the formula:

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

Substituting the given values into the formula:

Mass Fraction of Salt = 15 g / 260 g

Calculating this expression gives us the mass fraction of salt in the solution.
