A full can of soda has a mass of 0.421 kg. It contains 3.57 x 10-4 m3 of liquid. Assuming that the soda has the same density as water, find the volume of aluminum used to make the can.
Volume of liquid
mass of liquid
mass of aluminium (can)
density of aluminium = 2.7 g/ml
Volume of aluminium = 64/2.7 cc
= 23.7 cc
