Consider two liquids: liquid A, with a density of 0.98 g/mL, and liquid B, with a density
Question:
Consider two liquids: liquid A, with a density of 0.98 g/mL, and liquid B, with a density of 1.03 g/mL. Notice that one density is known to have two significant figures and the other to have three. Calculate the volume of liquid A in a sample that weighs 9.9132 g; be sure to express your result to the proper number of significant digits. Calculate the volume of the same mass of liquid B, again making sure that you have the appropriate number of significant figures. Recording the number of significant figures is only one way to estimate the uncertainty. Repeat the calculations of volume by using the minimum and maximum values of density to calculate maximum and minimum volumes. Th e range between the two is also a measure of uncertainty. Compare the estimated uncertainties in the two liquids as measured by the two techniques. Do all estimates give the same answer? Should they? Explain any disagreements.
