Assume the data below was collected for two different sample solutions using the same experimental procedure you carried out. Based on the two lines shown below, which solution (orange data points or blue data points) corresponds to the sample that would look DARKER in terms of how much light goes through the glass. 0.9 y= 4.7713x - 0.0728 R0.99953 0.8 0.7 0.6 0.5 0.4 0.3 0.2 y1.414x - 0.0546 R0.99642 0.1 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0.2 0.1 [Concentration, M] orange data points (lower line) blue data points (upper line) Absorbance
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of glycerol, carbon tetrachloride, pentane, tetrahydrofuran, and acetone. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density glycerol -3 1.3 g-cm - 3 1.6 g cm carbon tetrachloride -3 0.63 g·cm pentane tetrahydrofuran -3 0.89 g·cm -3 0.79 g·cm acetone Next, the chemist measures the volume of the unknown liquid as 0.786 L and the mass of the unknown liquid as 991. g. Calculate the density of the liquid. Round your g. cm answer to 3 significant digits. yes Given the data above, is it possible to identify the liquid? no glycerol carbon tetrachloride pentane If it is possible to identify the liquid, do so. tetrahydrofuran acetone
Suppose you prepared a plot for this experiment and the equation of the trendline was y = 78.012x+0.01251 Based on this information, what would be the absorbance of the solution if the concentration is 0.009697 M? DO NOT include units in your answer. Follow sig. fig. rules as you perform your calculations, but DO NOT round your answer until the very end of your calculation. Credit will only be given for answers that have the correct value and significant figures.
A student calibrated a eudiometer by first recording the mass of the empty eudiometer followed by filling the eudiometer to the 50.00 mL line with deionized water at 22°C and recorded the mass. The mass of water was 49.012 g. In an experiment run at 22°C, a reading from the eudiometer of 46.78 mL corresponds to what true volume?
