It seems like your question is incomplete. To help you with a step-by-step guide, I need more information about the substances you're preparing, the measurements you're taking, and the specific variables you're plotting. Here's a general guide based on your question:

1. Prepare a series of solutions with varying concentrations of the substance you're studying. The substance should be one that absorbs light at the wavelength you're using in your spectroscopy experiment.

2. Use your spectrometer to measure the absorbance of each solution at the specific wavelength.

3. Create a plot with the concentration of the substance on the x-axis and the absorbance on the y-axis. Each solution should be a point on the graph.

4. Use a statistical method (like least squares) to find the best-fit line for your data points. This line is your calibration curve.

5. You can now use this calibration curve to find the concentration of the substance in an unknown solution. Measure the absorbance of the unknown solution, find that value on the y-axis of your graph, and draw a line to the best-fit line. The x-value where it intersects is the concentration.

Please provide more details if you need a more specific guide.
