1) How can you use a table to determine the half-life? 2) How can you use a graph to determine the half-life? 3) Which method do you consider most appropriate for determining half-life? 4) If you had a graph of the total sample that had the original sample size at 64 g, and after 72 hours there were only 8 grams left of the substance, what would the half-life of the sample be? Thank you!!! :)
