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

Answer:

6.Given,

Final Velocity =60m/s

Initial Velocity= 0

Time=10 sec

A=?

A=Final Velocity- Initial Velocity/time

=60-0/10

=60/10

=6m/s ans.

Explanation:

Acceleration = Final Velocity - Initial Velocity/Time

By using this Formula we can calculate Acceleration.
