A student used an electronic balance to measure the mass of an empty 1.7-mL microcentrifuge tube and found that its mass was 1.025 g. She then pipetted a volume of
80.0 mL ethyl alcohol into the microcentrifuge tube and measured the final mass (1.080 g).
If the density of ethyl alcohol is 0.791 g/mL, what is the student's percent error?
