I need help completing this table regarding standard solution.
kramer

Answer:

The answer to your question is below

Explanation:

Data

Stock solution concentration = 0.00190 M

Volume stock solution = 10 ml

Final volume = 100 ml

Standard solution concentration = ?

Absorbance of the standard solution = 0.62

Process

A) 0.00190 M it was given in the data

B) 0.62            it was given in the data

C)                  C1V1  =  C2V2

                     C2 = C1V1/V2

                     C2 = (0.00190)(10)/100

                     C2 = 0.000190 M

D)   Ratio = Absorbance/Concentration = 0.62/0.000190

                                                                = 3263.2
