Question

В растворе массой 560г с массовой долей соли 2% растворили 50г соли.Чему равна массовая доля соли в полученном растворе?

Answer 1

M(соли в первом растворе)=560*0,02=11,2г
m(соли)=11,2+50=61,2г
массовая доля=61,2/560*100=10,9%=11%

Answer 2

Calculating the Mass Fraction of Salt in the Solution

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

Mass Fraction of Salt = (Mass of Salt / Total Mass of Solution) × 100%

Given: - Mass of the solution = 560g - Mass of the salt = 50g

Using the given values, we can calculate the mass fraction of salt in the solution.

Mass Fraction of Salt = (50g / 560g) × 100%

Mass Fraction of Salt = (50 / 560) × 100%

Mass Fraction of Salt ≈ 8.93%

Therefore, the mass fraction of salt in the obtained solution is approximately 8.93%. This calculation is based on the provided information and the formula for calculating the mass fraction of a substance in a solution.
