A sample of lead (Pb) has a volume of 5 cm3 and a mass of 56.5 g. What is
the density of lead?

Hey there!

The formula for density is d = m/v.

The mass of the sample is 56.5 g, and the volume of the sample is 5 cm³.

So, to plug these values into the equation, we have:

Simplified, this is:

d = 11.3

The unit for this is g/cm³, or grams per cubic centimeter.

So, the density of lead is 11.3 g/cm³.

Hope this helps!
