Question

В растворе массой 200г содержится серная кислота массой 18г определить массовую долю раствора

Answer 1

W= m вва×100% / м рра =1800/200= 9%

Answer 2

Calculating the Mass Fraction of the Solution

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

Mass Fraction = (Mass of Solute / Total Mass of Solution) * 100%

Given: - Mass of the solution (total mass) = 200g - Mass of the solute (sulfuric acid) = 18g

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

Mass Fraction = (18g / 200g) * 100%

Mass Fraction = (0.09) * 100%

Mass Fraction = 9%

Therefore, the mass fraction of the solution is 9%.

This calculation is based on the provided information and the formula for calculating the mass fraction of a solution
