and unkcaiculate peak area ratio of I pentanol to internal standard for all sandard solutions. Take average of two measurements of each solution. Step 3. Make a table showing all results of step 1 and 2. YOU MUST RECORD ALL CALCULATIONS IN YOUR LAB NOTEBOOK. Step 4. Prepare a standard calibration curve by plotting peak area ratios agains 1-pentanol concentrations (unit: mg/mL). Use Excel. The computers located in 1215 Gilman are loaded with these programs for your calculation. YOU MUST ATTACH A COPY OF THIS STANDARD CALIBRATION PLOT IN YOUR LAB NOTEBOOK. Step 5. Use the slope and intercept from the regression program of the standard calibration curve to calculate the amount of 1-pentanol (in mg) in the unknown obtained from your TA. Step 6. Submit the result reporting form showing the amount of 1-pentanol (in mg) in your unknown on Canvas.
