Student B 7. c. Three students were asked to determine the volume of a liquid by a method of their choosing. The calculator display shows the answer as 0.571429. a.mL(g/mL)gexample,for:unitsVolume 6. Considering the average of all three trials, which students measurements show the greatest accuracy? No c. How many significant figures are present in this measurement? 8. If you divide a samples mass by its density, what are the resulting units? A sample thought to be pure lead occupies a volume of 15.0mL and has a mass of 160.0 g. The table below shows the results. A certain sample with a mass of 4.00 g is found to have a volume of 7.0 mL. Match the description on the right to the most appropriate quantity on the left.

Use scientific notation toreport the value, showing an appropriate number of significant figures.7.1 Introduction: Recall from Chapter 1 that solutions are defined as homogeneous mixtures that are mixed so thoroughly that neither component can be observed independently of the other. Solutions are all around us. Air, for example, is a solution. If you live near a lake, a river, or an ocean, that body of water is not pure H 2 O but most probably asolution.
