3 pts D Question 5 After creating her standard curve for absorption versus the concentration (M) of FD&C Red 40, a student found that her best fit linear line for FD&C Red 40 was y = 2,774x + -0.009. Her Kool Aid sample had an absorbance of 0.848. If 0.465 grams of Kool Aid powder was used to prepare an 8-fl oz cup of her assigned flavor, what is the percent by mass of FD&C Red 40 in her 8-fl...

Question 5 1 pts Keep in mind that the absorbance was plotted on the y-axis and concentration of Fe in mg/mL was plotted on x-axis to get best-fit line equation from the standard solutions. If the best fit line equation is y = 100x +0.01 What is the Fe concentration in mg/mL if the absorbance is 0.4 based on the best-fit line equation? Keep two sig figs for your answer. The Total Cereal has a Fe concentration of 0.6 g...
