Question

Масса меди объемом 15 см в кубе равна 133,5 г.Чему равна масса меди объемом 22 см в кубе?

Answer 1

Ответ:

133.5:15 = 8.9 (см3) - 1см

8.9 * 22 = 195.8(см3)

Ответ: 195.8 см3

Answer 2

To find the mass of copper (медь) with a volume of 22 cm³, we can use the concept of density. Density is defined as mass per unit volume and is typically denoted by the symbol "ρ" (rho).

The formula for density is:

Density (ρ) = Mass (m) / Volume (V)

Given:

• Mass of copper (m1) = 133.5 g
• Volume of copper (V1) = 15 cm³

We can rearrange the formula to solve for the mass (m2) of copper with a volume of 22 cm³:

m2 = ρ * V2

Now, we need to find the density of copper, which remains constant regardless of the volume.

Density of copper (ρ) = m1 / V1

Substitute the given values:

Density of copper (ρ) = 133.5 g / 15 cm³

Now, calculate the density:

ρ ≈ 8.9 g/cm³

Now, we can find the mass of copper (m2) with a volume of 22 cm³:

m2 = 8.9 g/cm³ * 22 cm³

Calculate:

m2 ≈ 195.8 g

Therefore, the mass of copper with a volume of 22 cm³ is approximately 195.8 grams.
