Question

Use the trend line A= 17453C + 0.0745 to calculate the concentration of a solution that has an absorption of 1.0, where A and C are absorption and concentration, respectively.

Answer 1

To calculate the concentration of a solution with an absorption of 1.0 using the given trend line A = 17453C + 0.0745, substitute the value of A into the equation and solve for C. The concentration of the solution is approximately 0.000053 M.

Step-by-step explanation:

To calculate the concentration of a solution that has an absorption of 1.0 using the given trend line A= 17453C + 0.0745, we can substitute the value of A into the equation and solve for C.

1.0 = 17453C + 0.0745

Subtracting 0.0745 from both sides, we get:

0.9255 = 17453C

Dividing both sides by 17453, we find that:

C ≈ 0.000053 M

Hence, the concentration of the solution is approximately 0.000053 M.
