The mass of 10 cm^3 of iron is 79 g. What is its density?

Answer: d = 7.9 g/cm^3

Identify the given information.

m = 79 g

v = 10 cm^3

Choose which formula you should use. In this case, you are finding the density.

d = m/v

Substitute and solve.

d = 79 g/10 cm^3

d = 7.9 g/cm^3

We can solve this problem by using the density-mass-volume relationship:

Density=mass divided by volume

7.9 = 25.28 divides by v

V = (25.28 divided by 7.9)

V = 3.20cm^3

Therefore, 25.28 g of iron, with a density of

7.9 g divided by cm^3

occupies a volume of 3.20cm^3
