(0) While assisting in the laboratory, you have been tasked to help determine the cause of an upset in a fractionation tower. It is believed that it is to do with an increase in propane in the feed. The analyst has completed the analysis and wants you to quantify the propane concentrations from the sample. She hands you the following calibration curve and tells you that she did a 5x dilution during sample preparation. If the instrument response was 5.32, what is the propane concentration?8 7 6 5 4 y = 0.0879x - 0.0297 Series 1 Instrument response propane 1 0 50 100 150 Analyte concentration (parts per million)

Also, should be divide by 5 or times 5?
