Question

How much mass would a sample of magnetite, a magnetic stone, with a volume of 8 cm^3 and a density of 5 g/cm^3 have?

Answer 1

given,

volume of sample of magnetite = 8cm^3

Density of sample of magnetite = 5g/cm^3

We know that ,

Density of sample = mass of sample/volume of sample

Now ,

Mass of sample = density of sample x volume of sample

Mass of sample of magnetite= 5g/cm^3 x 8cm^3 = 40 grams (g)
