Question

В 65 г воды растворили 35 г сахара Какова масса доля сахара в полученном растворе​

Answer 1

Ответ:

35%.

Пошаговое объяснение:

$w = \frac{m}{m_{p-pa}}$

$w(C_{12}H_{22}O_{11}) = \frac{m(C_{12}H_{22}O_{11})}{m_{p-pa}} = \frac{35}{35+65} = 0.35$ или 35%.

Answer 2

Calculating the Mass Fraction of Sugar in the Solution

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

Mass Fraction = (Mass of solute / Total mass of solution) x 100%

Given: - Mass of water = 65 g - Mass of sugar = 35 g

Using the given formula, we can calculate the mass fraction of sugar in the solution:

Mass Fraction of Sugar = (35 g / (65 g + 35 g)) x 100%

Mass Fraction of Sugar = (35 g / 100 g) x 100%

Mass Fraction of Sugar = 35%

Therefore, the mass fraction of sugar in the obtained solution is 35%.
