This is not a graded assignment, this is a question from a worksheet that I am teaching, and I wanted to check my answers please:On a graph of Absorbance and Concentration. There are three data points in addition to (0,0). The first point is 0.189 Absorbance for 2x10^-6MThe second is 0.378 Absorbance for 4x10^-6MThe third and last is 0.634 Absorbance for 6x10^-6M (slightly above the trendline) a) If you recorded an absorbance of 0.525, calculate the corresponding molarity of the solution. b) If the molar mass of the dye used was 791.41 g/mol, how many grams of dye were dissolved in 10.0 mLof the solution measured in part a? c) What is the calculated absorbance for a solution with a concentration of 1.5x10-6 M? d) Propose a logical reason for the error that occurred with the data point at 6.0 x10-6 M.

On a graph of Absorbance and Concentration. There are three data points in addition to (0,0).
The first point is 0.189 Absorbance for 2x10^-6M
The second is 0.378 Absorbance for 4x10^-6M
The third and last is 0.634 Absorbance for 6x10^-6M (slightly above the trendline)
a) If you recorded an absorbance of 0.525, calculate the corresponding molarity of the solution.
b) If the molar mass of the dye used was 791.41 g/mol, how many grams of dye were dissolved in 10.0 mL
of the solution measured in part a?
c) What is the calculated absorbance for a solution with a concentration of 1.5x10-6 M?
d) Propose a logical reason for the error that occurred with the data point at 6.0 x10-6 M.
