Brass is a yellow alloy formed from copper and zinc. A brass cylinder has a length of 2.14 in and a diameter of 0.78 in. What is the mass of brass in this cylinder?
You may assume that brass is 61 % copper (density is 8.84 g/mL) and the rest is zinc (density is 7.18 g/mL)
Use the concept of weighted density here to get an idea of density of brass and assume that the density of brass varies linearly with composition.
