If the density of a diamond is 3.15 g/cm3 then what is the mass of a 25cm diamond?

78.75g

Explanation:

The density of diamond is the mass of diamond per unit of its volume. The density of a substance is calculated using the formula:

Density (g/cm^3) = mass (g) / volume (cm^3)

According to the question, the density of diamond= 3.15g/cm^3, volume of diamond= 25cm^3, mass = ?

Hence, to calculate the mass, we say;

Mass = Volume × density

Mass = 25 × 3.15

Mass = 78.75

Therefore, the mass of diamond is 78.75grams.
