To identify a liquid substance, a student determined itsdensity. Using a graduated cylinder, she measured out a 45-mLsample of the substance. She then measured the mass of thesample, finding that it weighed 38.5 g. She knew that the substancehad to be either isopropyl alcohol 1density 0.785 g>mL2or toluene 1density 0.866 g>mL2. What are the calculated densityand the probable identity of the substance?

One student calibrated a 50-mL burette by using the mass of water delivered. The student used an analytical balance which was previously calibratedby STEEL (density = 7.8 g/mL). During calibration, the temperature of water was found to be 19.0oC. The density of water at this temperature is0.9984 g/mL. The results of the calibration by the student is shown in the table below:A B C D EApparent burette reading, mL 10.05 20.04 30.08 40.07 49.98Weight H2O delivered, g 10.03 20.09 30.05 40.02 49.83Note: All masses in mentioned in this section are understood to be in grams and all volumes mentioned are understood to be in milliliters. a) What is the true volume of water delivered in B?
