Question

Please answer the question correctly is all I want and explain why its thats answer for the final and please answer as quickly as possible, thanks!

You graph the calibration curve of a solution of an unknown metal (we will call it M+) at 400 nm. The graph is shown below. What is the concentration the solution with an absorbance of 0.500 at 400 nm?

140 mmol/L
1.6 mmol/L
165 mmol/L
330 mmol/L

Expert Solution

Step 1

To calculate value of concentration, we can use the graph. For this use the given value of absorbance and draw an straight line to the line of the curve. Then draw an line to the x-axis. This would give value of concentration at given absorbance.
