An irregular metal specimen is to be investigated for its density using the water‑displacement method. The balance available has a least count of 0.01 g and the graduated cylinder has a least count of 0.5 mL. The student records the following readings:

Question Parts

( a )
The mass of the empty container is 50.12 g and the combined mass of container plus specimen is 150.23 g. Determine the mass of the metal specimen, stating the appropriate uncertainty.
( b )
The initial water level in the cylinder is 200.0 mL and after immersing the specimen it reads 215.5 mL. Calculate the volume of the specimen and give its uncertainty.
( c )
Determine the density of the metal specimen, expressing the result with the correct number of significant figures.
( d )
Estimate the percentage uncertainty in the density using the given uncertainties and list two possible systematic errors that could affect the result.
