Use the data in the table to calculate the % mortality and % concentration used in the toxicity study. Graph the dose-response curve for the data in the table. Assume that each concentration exposure starts with 78 live organisms. Based on the dose-response curve graph that you made, the approximate LC50 for this contaminant is:
