Question

Определить массовую долю вещества в растворе для приготовления которого взяли 17 г хлорида бория и 200 г воды.ПОЖАЛУЙСТА.заранее спасибо

Answer 1

Ну тогда так.........

Answer 2

Calculating the Mass Fraction of a Substance in a Solution

To determine the mass fraction of a substance in a solution, we can use the following formula:

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

Given: - Mass of Boron Chloride (BCl₃) = 17 g - Mass of Water (H₂O) = 200 g

Using the formula, we can calculate the mass fraction of boron chloride in the solution.

Mass Fraction of BCl₃ = (17 g / (17 g + 200 g)) × 100%

Mass Fraction of BCl₃ = (17 g / 217 g) × 100%

Mass Fraction of BCl₃ ≈ 7.83%

Therefore, the mass fraction of boron chloride in the solution is approximately 7.83%.
