Question
A student found that a brass cylinder weighs 74.04g in air and 66.11g in water (density 0.998g/cm3). What is the density of brass?

the cylinder displaces (74.04 g - 66.11 g) of water
divide the mass of the displaced water by the given density
... this gives the volume of the cylinder
divide the weight of the cylinder by the volume ... this is the density
divide the mass of the displaced water by the given density
... this gives the volume of the cylinder
