Question

Некоторые люди любят пить ароматизированный травяной чай и используют для его приготовленияMAразведённую в воде густую вытяжку из душицы имать-и-мачехи. Плотность травяной вытяжки1,1 г/см3, плотность воды 1 г/см3.Для приготовления раствора смешали воду итравяную вытяжку в отношении 4:1.Найдите плотность полученного раствора, если егообъём равен сумме объёмов исходных компонентов.​

Answer 1

Ответ:

5m/p=4m/p₁ + m/p₂

$p=\frac{5p_{1}P_{2}}{p_{1}+4p_{2}}$

p=1.0185 г/см³

Answer 2

Calculating the Density of the Solution

To find the density of the solution, we can use the formula:

Density = (mass of component 1 + mass of component 2) / (volume of component 1 + volume of component 2)

In this case, the components are the water and the herbal extract. The volumes of the components are equal, so we can simplify the formula to:

Density = (mass of water + mass of herbal extract) / (2 * volume of water)

Calculating the Mass of Water and Herbal Extract

First, let's calculate the mass of water and herbal extract.

The volume ratio of water to herbal extract is 4:1. This means for every 4 units of water, there is 1 unit of herbal extract.

Given that the density of the herbal extract is 1.1 g/cm³ and the density of water is 1 g/cm³, we can calculate the mass of each component.

Mass of Water:

Volume of water = 4x Mass of water = Density of water * Volume of water

Mass of Herbal Extract:

Volume of herbal extract = x Mass of herbal extract = Density of herbal extract * Volume of herbal extract

Calculating the Total Mass and Density of the Solution

Now that we have the masses of water and herbal extract, we can calculate the total mass and the density of the solution.

Total Mass = Mass of water + Mass of herbal extract

Finally, we can use the formula for density to find the density of the solution:

Density = Total Mass / (2 * Volume of water)

Let's calculate the values using the given information.
