Student practical assignment on the densities of metals
Your task is to identify these three metallic elements by determining their densities, using measurement and weighing. When your have calculated the densities from the volumes and masses, you can look up tables of densities on the Internet, to identify the metals.
Each division on the ruler is 1cm and the top pan balance reads grammes. Each mass of metal has a square base. You can use the mouse to drag the masses and the ruler.
When you are measuring the dimensions of the masses, take care to estimate the values as accurately as possible as a small error here will be significant.
