You are required to determine the density of an unknown metal using the water‑displacement method. The metal specimen is first weighed on an electronic balance and then its volume is measured by the rise in water level in a graduated cylinder. The following data are recorded: - Mass of metal (m) = 45.62 g - Initial water volume = 150.0 mL - Final water volume after immersion = 165.3 mL - Temperature of water = 22 °C (density of water at 22 °C = 0.9978 g mL⁻¹) Answer the questions below.

Question Parts

( a )
Calculate the volume of the metal specimen in cubic centimetres (cm³).
( b )
Determine the density of the metal in kg m⁻³, showing all steps of unit conversion.
( c )
State two possible sources of error in this experiment and suggest a method to reduce each error.
( d )
If the metal is identified as aluminium (standard density 2700 kg m⁻³), comment on the accuracy of your result.
