an experiment was preformed under identical conditions as yours.The absorbance of the penny solution was recorded as 0.231absorbance units. A calibration plot of absorbance vs concentrationof cu(II) (mM) yielded the following trendily equations y= 11591x+.50
a. What is the concentration of the original penny solution?
b. How many grams of Cu are in this solution?
c. if the percent Cu was determined to be 2.70 percent what wasthe mass of the penny?
