Answer:
From the linear regression analysis of y=4.8811x+0.1453 we calculate the starch concentration by rearranging the formula to x=(y- 0.1453)/4.8811.
Explanation:
The starch concentration of the sample is 0.159 mg/mL. The dilution factor was 1:10 making it a concentration of 1.59 mg/mL. For each cuvette concentration calculation, multiply the concentration of the diluted starch solution in the Erlenmeyer flask by the volume of the diluted starch solution you added to the cuvette. Then, divide by the total volume of liquid you placed in the cuvette, which is 5 mL.
I hope this helps you! :) I'd appreciate brainliest. but if there's a better answer, vote for that one.
