3. A student uses a stoppered 25.0-mL volumetric flask to determine the density of a liquid.
The mass of the empty flask and stopper was 25.1841 g. The mass of the stoppered flask
filled with liquid up to the scratch mark was 45.0379 g. Calculate the density of the
liquid in appropriate units and with the correct number of significant figures.
4. Calculate the error and percent error of a sample of water using the following data: the
actual density of water at 23 °C is 0.999765 g mL-1 and the experimental density (at 23
°C) is 1.097 g mL-1. Show your work and watch your significant figures.
