One group studied liquid A and found that 65.0 mL weighed 77.84 g. The other group found that 26.3 mL of liquid B weighed 31.49 g. Based on these findings, which statement is correct (use the correct number of significant figures). su Ex sta i) The density of liquid A is greater than that of liquid B. ii) The density of liquid A is equal to that of liquid B. iii) The density of liquid A is less than that of liquid B. 2. What is the purpose of creating a calibration curve of density vs. percent sugar? 3. Attach a copy of your graph and your best fit line. a) Since the graph is a straight line, derive an equation (y = mx + b) to determine your % sugar content in your unknowns. Show a sample calculation below to determine the % sugar from one of the unknowns you worked with. %3D b) Estimate this value from your graph by showing and labeling the point on the graph. 4. What would be the percent sugar if the density reading were 1.025 g/mL in your experiment? Img
