Problem
To identify a liquid substance, a student determined its density. Using a graduated cylinder, she measured out a 45-mL sample of the substance. She then measured the mass of the sample, finding that it weighed 38.5 g. She knew that the substance had to be either isopropyl alcohol (density 0.785 g/mL ) or toluene (density 0.866 g/mL ).


Is a graduated cylinder such as that shown on the left The figure shows a graduated cylinder. The volume of liquid is 100 milliliters. The cylinder has the following graduations: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100. likely to afford the accuracy of measurement needed?
