Ameteorite contains 0.17 g of nickel-59, a radioisotope that decays to form cobalt-59. the meteorite also contains 5.27 g of cobalt-59. how many nickel-59 half-lives have passed since the meteorite formed? a. 1 b. 5 c. 5.1 d. 5.44

B. 5

Explanation:

The half-life of the nickel-59 is 76000 years. The initial mass of the radioisotope is:

The time constant for the radioisotope is:

The decayment rate is given the following expression:

(5 half-lives).

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
