What is the density of a sample of charcoal with a mass of 3.0 g and a volume of 10 cm³?

A. 0.3 g/cm³
B. 3.3 g/cm³
C. 7 g/cm³
D. 30 g/cm³

Respuesta :

The carbon has a mass of 3.0 g and a volume of 10 cm³. So we will calculate the density. The formula to calculate its density is:

d = m/v

We substitute the data in the formula and solve:

d = 3.0 g/10 cm³

d = 0.3 g/cm³

Therefore the density of the carbon sample is 0.3 g/cm³. Opction "A".
