What is the concentration of the AR stock solution in ppm? Using the molar mass of AR (496.42 g/mol), and that 1 ppm = 1 mg/L, convert this ppm concentration to μM. Assume the density of the solution is 1.000 g/mL. Concentration of AR Stock Solution (ppm) Concentration of AR Stock Solution (μM) 21.22 Unrounded 3 Rounded 3

If a total of 125 mL of a 10% solution is diluted to 500 mL in a 500-mL volumetric flask, what is the concentration of the resulting new solution?   You are asked to make a 1/2 dilution using 1.5 mL of serum. How much diluent do you need to use?  If you make a five-tube twofold dilution using 2 mL of serum, what is the concentration of serum in tube #4?

If a sample of water is being determined to contain 389 ppm of lead, how many g of lead does one gallon (1 gal = 3785 g of water) of this lead contaminated water contain? Round your answer to 4 decimal digits.

Solution 1 is diluted by adding 519 microliters of Solution 1 to 5 mL of Solution 2. What is the dilution of Solution 1?   Report your answer in standard decimal notation rounded to 2 decimal places. Include trailing zeros so that two decimal points are reported. For example, 500 μL added to 5 mL would be a 0.09 dilution or 50 μL added to 4.5 mL would be a 0.10 dilution.
