Exactly 5.00-mL aliquots of a methanol solution containing an unknown amount of methamphetamine were measured into 50.00-mL volumetric flasks. The following volumes of a standard methanol solution of methamphetamine containing 2.000 ug/mL of methamphetamine were then introduced into each flask and the mixture was diluted to volume with 0.000, 0.500, 1.00, 1.50 and 2.00 mL of methanol. 1 uL of these solutions was then injected into a gas chromatograph and the following respective peak areas were measured: 326, 480, 641, 802, and 956 (all peak areas were x 103). Plot the data Using the plot from (a), calculate the concentration of methamphetamine in the unknown. Derive a least squares equation from the data. Calculate the concentration of methamphetamine from the equation in (c).
(Concentration) You are tasked to prepare 50.000 ppm of a caffeine standard for an analysis. If you need to prepare 500.00 (±0.08) mL of this solution, how much (in grams) solid, pure caffeine are you supposed to dissolve? What absolute uncertainty is associated with your mass measurement if the prepared solution has a 0.12% percent relative uncertainty? Write your answer using the appropriate number of digits. Note that the formula mass of caffeine is 194.194 g/mol with negligible error. (absolute error) How many significant figures does your reported mass have? --- (number of sig. figs.)

To quantify the amount of ethanol in a beverage, a technician prepared the first solution which contained 4.90 grams unknown, 1.00 grams acetonitrile, and 4.10 grams water. After the GC analysis which reported the peak areas of 5,742 for ethanol and 3,829 for acetonitrile, the technician added 0.20 grams ethanol to the first solution and ran the GC analysis again. This time, the peak areas of 6,382 for ethanol and 3,709 for acetonitrile for solution 2 were obtained. What was the percent by mass ethanol in the original beverage?
A pheromone is a type of volatile compound produced by a variety of insect species for chemical communication. These molecules can be used to signal alarm, to attract a mate, or to indicate the presence of food. The presence of 1.00 x 10-8 g of a pheromone can be sensed by another insect within a radius of 0.500 miles. Calculate the density of this pheromone. (1609 m = 1 mile) %3D Calculate the density (g/L) of the pheromone in this cylindrical air space.

Complete the table by entering the molarity of B2- for each standard solution. Show an illustrative calculation for tube ‘A’. Use the dilution formula and express each result to one more digit than allowed by applying the rules of significant figures. Standard Volume of stock B2- solution taken, mL Molarity of dilute B2 Construct a graph of Absorbance vs. molarity of B2- in Excel using the data in the preceding table. Make certain to title the graph and include axes labels with proper units. Absorbance is dimensionless (has no unit). Add a linear trendline to the graph but do not set the y-intercept to zero Solid M2B is added to 25 mL of water, the resulting mixture is continually stirred for 1 hour. At this point, it is assumed that equilibrium (eqn 3) has been established. The mixture is transferred to a test tube, and the test tube is centrifuged to assure that any residual solid M2B is fully settled out. A portion of the supernatant in the test tube is carefully…
