An irregularly shaped metal object is to be investigated for its density using the water‑displacement method and a top‑loading balance.

Question Parts

( a )

The mass of the object is measured on a balance that reads 125.6 g. State the least count of the balance and write the mass of the object correct to the appropriate number of significant figures.

( b )

The object is then gently placed in a graduated cylinder containing water. The initial water level is 250.0 mL and the final level after immersion is 285.5 mL. Determine the volume of the object in cm³, stating any assumptions made.

( c )

Calculate the density of the metal object in g cm⁻³ and give your answer to three significant figures.

( d )

Identify two possible sources of systematic error in the experiment and suggest a practical way to minimise each error.
