A) What would have happened if the commercial product was used instead of the stock solution to make the calibration standards (dilutions)? Would the results be valid? Explain why or why not.
B) A student uses the red dye to create the calibration graph. Then the student uses that same graph to determine the concentration of dye in the blue Crest mouthwash solution. Would the results be valid? Explain why or why not.
C) Suppose you were to determine the density of a solid and gasâhow will the procedures and results differ from that of a liquid? Note: a good answer will address procedure differences between all three states of matter and will compare density results for all three states of matter.
D) As student measures the density of a stock solution and two standard mixtures (dilutions). One of the dilutions has a higher density than the stock. Does this data make sense? Why or why not? Explain the relationship between molarity, moles, and volume. Explain the relationship between stock solution and standard mixtures
