A solid metal cylinder is to be investigated for its density using the water‑displacement method. The mass of the cylinder is measured on a balance and the volume is obtained by noting the rise in water level in a graduated cylinder.

Question Parts

( a )
Calculate the density of the cylinder in g cm⁻³. (Mass = 150.0 g, water level rises from 50.0 mL to 62.5 mL)
( b )
The accepted density of copper is 8.96 g cm⁻³. Determine the percent error of the experimental density obtained in part (a).
( c )
State two possible sources of error in the experiment and suggest one practical way to reduce each error.
