Question

ПОМОГИТЕ СРОЧНО, У МЕНЯ ВПР!!! Некоторые люди любят пить зимой витаминный напиток-сок из чёрной смородины, смешанный с медом. Плотность сока равна 1 г/см³, а плотность меда в полтора раза больше плотности сока. 1) Определите плотность меда. 2) Какова плотность такой смеси, если в 1000 г сока растворили 375 г меда? При растворении меда в соке объем смеси можно считать равным сумме объемов исходных компонентов смеси.​

Answer 1

1)
Плотность меда:
ρ₂ = 1,5·ρ₁ = 1,5·1 = 1,5 г/см³
2)
m₁ = 300 г - масса сока
m₂= 300 г - масса меда
Объем сока:
V₁ = m₁ / ρ₁ = 300 / 1 = 300 см³
Объем меда:
V₂ = m₂ / ρ₂ = 300 / 1,5 = 200 см³
Масса смеси:
m = m₁ + m₂ = 300 + 300 = 600 г
Объем смеси:
V = V₁ + V₂ = 300 + 200 = 500 см³
Плотность смеси:
ρ = m / V = 600 / 500 = 1,2 г/см³

Answer 2

Calculation of Honey Density:

To determine the density of honey, we need to know that the density of the juice from blackcurrant is 1 g/cm³ and the density of honey is 1.5 times greater than the density of the juice.

1) To find the density of honey, we can multiply the density of the juice by 1.5:

Density of honey = Density of juice * 1.5

Density of honey = 1 g/cm³ * 1.5

Density of honey = 1.5 g/cm³

Therefore, the density of honey is 1.5 g/cm³. [[1]]

Calculation of Mixture Density:

To calculate the density of the mixture, we need to know the mass of the juice and the mass of the honey that are mixed together.

2) Given that 1000 g of juice is mixed with 375 g of honey, we can calculate the total mass of the mixture:

Total mass of the mixture = Mass of juice + Mass of honey

Total mass of the mixture = 1000 g + 375 g

Total mass of the mixture = 1375 g

Since the volume of the mixture can be considered equal to the sum of the volumes of the original components, we can calculate the density of the mixture using the formula:

Density of the mixture = Total mass of the mixture / Total volume of the mixture

The total volume of the mixture is not provided in the question, so we cannot calculate the density of the mixture without this information.

Please provide the volume of the mixture in order to calculate its density.
