The volume of a piece of copper is 14.2 cm3. A student measures its mass using an electronic balance, obtaining a reading of 127 g.
The student notices that the electronic balance has a zero error, so it shows mass readings that are all slightly too large.
This means that the calculated density value is:
incorrect and slightly too large
incorrect and slightly too small
correct because the student used three significant figures
correct because the mass of the block is more than zero
