b. At what time(s) does the lowest number of cars pass through the intersection?
c. Briefly describe the trend in numbers of cars over the course of the day.
d. Provide a hypothesis explaining the trend in numbers of cars over the course of the day.
e. Provide a possible experiment that could test your hypothesis.

- You can analyze for a copper compound in water using an instrument called a spectrophotometer. [A spectrophotometer is a scientific instrument that measures the amount of light (of a given wavelength) that is absorbed by the solution] The amount of light absorbed at a given wavelength of light (A) depends directly on the mass of compound per liter of solution. To calibrate the spectrophotometer, you collect the following data: Plot the absorbance (A) against the mass of copper compound per liter (g/L), and find the slope (m) and intercept (b) (assuming that A is y and the amount in solution is x in the equation for a straight line, y = mx + b). What is the mass of copper compound in the solution in g/L and mg/mL when the absorbance is 0.635?arrow_forwardWhy is the ability to solve problems important in the study of chemistry?
