The table shows the amount of radioactive element remaining in a sample over a period of time.
Radioactive Decay Rate
Amount of Radioactive Sample(grams) Time(hours)
186.0 \0
147.0 \7
117.0 \14
93.0 \21
23.3 \63
Part 1: What is the half-life of the element? Explain how you determined this.
Part 2: How long would it take 320 g of the sample to decay to 2.5 grams? Show your work or explain your answer.
