What is the mass of a cylinder of lead that is 2.50 cm in diameter and 5.50 cm long. The density of lead is 11.4 g/mL. Find the volume of the cylinder.

Recall that density of a material can be solved by

d = m/V

where:

m = mass of material

V = volume of material

Note that the volume of a cylinder is given by

V = pi*(r^2)*h

where:

r = radius (which is 1/2 of the diameter)

h = height

Substituting,

V = 3.14*[(2.50/2)^2]*5.50

V = 26.98 cm^3

d = m/V

Note that mL is equivalent to cm^3. Thus

11.4 = m/26.98

m = 11.4*26.98

m = 307.57 g

Hope this helps~ :)
