Question

a sample containing 33.42g of metal pellet is poured into a graduated cylinder initially containing 12.7 ml of water, causing the water level in the cylinder to rise to 21.6ml. calculate the density of the metal in g/cm^3

Answer 1

Mass of metal pellet=33.42g
Volume of water only=12.7ml
Volume of water and metal pellet=21.6ml
Volume of metal pellet only=21.6ml-12.7ml=8.9ml
Iml=1cm^3
Mass=33.42g
Volume=8.9cm^3
Density=mass/volume=33.42/8.9=3.755g/cm^3
