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(years)
56.0 - 0
47.1 - 400
39.6 - 800
33.3 - 1,200
28 - 1,600
Part 1: What is the half-life of the element? Explain how you determined this.
Part 2: How long would it take 312 g of the sample to decay to 9.75 grams? Show your work or explain your answer.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
