Part A Phosphorus-32 has a half-life of 14.0 days. Starting with 8.00 g of 32P, how many grams will remain after 112 days ? Express your answer numerically in grams.
Part B Carbon-14 has a half-life of 5730 years. In a plant fossil, you find that the 14C has decayed to 1/8.00 of the original amount. How long ago was this plant alive? Express your answer numerically in years.
