Question 1: Answer the following questions regarding half-lives. Assume first-order half life kinetics (2 pts total). A. The half-life of Co-60 is about 5.25 years. Starting with a 42 g sample, how much remains after 21.0 years have passed (1 pt)? B. The Spider that bit Miles Morales secretes an unknown radioactive chemical that decays via first order kinetics. Originally 27.0 mg, only 5.3 mg remains after 32 days. What is this compound's half-life (1 pt)?
