A student performs an experiment to determine the density of a sugar solution. She obtains the following results: 3.8 g/mL, 4.8 g/mL, 5.1 g/mL, 7.0 g/mL. If the actual value for the density of the sugar solution is 5.4 g/mL, which statement below best describes her results? Select one or more: a. It isn't possible to determine with the information given. b. Her results are neither precise nor accurate. c. Her results are accurate, but not precise. d. Her results are both precise and accurate e. Her results are precise, but not accurate.

arch F2 # 3 E D 1. Plot density versus concentration for the five reference solutions on a graph. The concentration is the independent variable (x-axis), and the density is the dependent variable (y-axis). Use a spreadsheet program or ruler to draw a "best-fit" straight line through the data points. II 2. Use the graph to estimate the unknown sugar concentration in each beverage. To do this, locate the point on the y-axis that corresponds to the density of the beverage. Follow that point on the y-axis horizontally to where it meets the best-fit straight line. Read down vertically from this point on the best-fit line to the x-axis to estimate the percent concentration of sugar in the beverage. Construct a Results Table and record the density of each beverage and its estimated percent sugar concentration.

A 55% sucrose solution lost 240 mL by evaporation. After evaporation what is the sucrose concentration in the remaining 300 mL? Round your final answer to 2 decimal places if necessary.

you are given 15ug/ml atrazine to prepare a 3 ppb solution  a. use te terms working and stock to describe the 2 solutions b. describe the 15 ug/ml atrazine solution in X terms c. what concentration would a 10X stock of atrazine be if you will use it at 3 ppb. You may express your answer in units of ppb.
