Ответ: 7.7г/см^3

Answer 2

Calculation of Density

To calculate the density of a material, we need to divide its mass by its volume. In this case, we have a metal with a mass of 500 g and a volume of 65 cm³.

The formula for density is:

Density = Mass / Volume

Let's substitute the given values into the formula:

Density = 500 g / 65 cm³

To find the density, we need to convert the units of mass and volume to a consistent unit. Let's convert grams to kilograms and cubic centimeters to cubic meters for easier calculation.

1 kg = 1000 g 1 m³ = 1000000 cm³

Converting the units:

Density = 0.5 kg / 0.000065 m³

Now, let's calculate the density:

Density = 0.5 kg / 0.000065 m³ = 7692.3077 kg/m³

Therefore, the density of the metal is approximately 7692.3077 kg/m³.

Please note that the calculation assumes the metal is homogeneous and has a uniform density throughout.
