Problem 1. In an experiment, a student erroneously used the molar mass for silver sulfate to calculate the concentration of silver in a titrant instead of using the correct molar mass for silver nitrate. 250.00 mL of the titrant were made. The student reported the concentration of silver ion as 0.7408 M $Ag^+$ based upon the molar mass of silver sulfate. a) Determine the mass of salt that was used to make the solution. (3 marks) b) Using the correct molar mass for silver nitrate, determine the actual concentration of $Ag^+$ in the solution. (3 marks) c) Based upon this error, if the incorrect concentration of silver ion was used to determine that there was 82.45% $CaCl_2$ in a sample, would the real value of $CaCl_2$ be larger or smaller than this value? Explain your reasoning. (2 marks)

8. One-dimensional steady-state flow is established through a column filled with sand. At time = 0 a dye is injected in the influent end of the column. Continuous injection of the dye results in a constant concentration at the influent end of the column. Samples were collected at the effluent (discharge) end of the column and were analyzed for dye concentrations. The following results were obtained, where $C/C_o$ is ratio of the output concentration to the input concentration. DATA: Column Length: 100 cm K: $10^{-3}$ cm/s n: 0.3 Cross-sectional area: 10 $cm^2$ (a) Sketch (on the above diagram) how this curve would look like if advection were the only transport mechanism. (5) (b) Determine the specific discharge (q) in the column. (10) (c) What caused mechanical dispersion? (5)

Kenny bought a 50-pound bag of chicken feed for $29.98 and a 25-pound bag for $15.49. Can you use proportional reasoning to find the price of a 40-pound bag? Select the correct response. A. Yes, the ratio of $29.98 to $15.49 is the same as the ratio of 50:25. B. Yes, the ratio of $29.98: 50 is the same as the ratio of $15.49:25. C. No, because there is a constant of proportionality. D. No, because there is no constant of proportionality.
