A student is trying to determine whether a solvent is benzene(0.877g/cm3) or acetone (density 0.785g/cm3)
measures out 26mL of a liquid solvent in a 50mL graduated cylinder that has ±1mL error. The mass of the
liquid sample is 20.972g. Assuming that the balance has only a 0.001g error.
a. Using the uncertainty in the volume, calculate the possible range of masses of the solvent. You
should have a high and a low mass for each solvent.
b. Which solvent is present? Explain
