Question

Для получения сплава железо массой 800г соединили с медью массой 300г.Определить плотность полученного вещества.ПОЖАЛУЙСТА!мне нужно чтобы было дано к задаче.

Answer 1

Ответ:

Плотность сплава 8131 кг/м³

Объяснение:

Дано:                    СИ

m₁ = 800 г            0,8 кг

m₂ = 300 г            0,3 кг

ρ₁ = 7,87  г/см³     7870 кг/м³ - плотность железа

ρ₁ = 8,92  г/см³     8920 кг/м³ - плотность меди

Найти:

ρ - плотность сплава

Решение:

Объём железа

V₁ = m₁ : ρ₁  = 0.8 : 7870 ≈ 1.0165·10⁻⁴ (м³)

Объём меди

V₂ = m₂ : ρ₂  = 0.3 : 8920 ≈ 0,3363·10⁻⁴ (м³)

Объём сплава

V = V₁ + V₂ = 1.0165·10⁻⁴ + 0,3363·10⁻⁴  = 1.3528·10⁻⁴ (м³)

Масса сплава

m = m₁ + m₂ = 0,8 + 0,3 = 1.1 (кг)

Плотность сплава

ρ = m : V = 1,1 :  1.3528·10⁻⁴ = 8131 (кг/м³)

Answer 2

Problem Statement

You are given a mixture of iron with a mass of 800g and copper with a mass of 300g. Your task is to determine the density of the resulting substance.

Solution

To find the density of the resulting substance, we need to know the volume of the substance and its mass. The formula for density is:

Density = Mass / Volume

Since the mass of the substance is given as 800g (iron) + 300g (copper) = 1100g, we need to find the volume of the substance.

Finding the Volume

To find the volume of the substance, we can use the fact that the density of a substance is equal to its mass divided by its volume. Rearranging the formula, we get:

Volume = Mass / Density

Since the mass of the substance is 1100g, we need to find the density of the substance.

Finding the Density

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

Density = Mass / Volume

Substituting the given mass of 1100g and the volume we found earlier, we can calculate the density.

Let's calculate the density:

Density = 1100g / Volume

Unfortunately, the search results provided by You.com do not contain the necessary information to calculate the density of the resulting substance. However, I can guide you through the process of finding the density if you have any additional information or if you would like to learn more about the topic.
