In this experiment, the problem is that the volume of the volumetric pipet is not accurately known (only 2 sig figs), so any density calculation will also be limited to 2 sig figs. Calibration increases the number of sig figs from 2 to 4. As a result, the density also increases from 2 to 4 sig figs. Explain how and why this is possible.
