The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 180 grams of a
radioactive isotope, how much will be left after 4 half-lives?
Use the calculator provided and round your answer to the nearest gram.
grams

Answers

Answer 1

Answer:

According to the definition of half-life, the mass of the radioactive isotope halfs its mass after each half-life, which means the remaining mass is always half the amount of the previous mass.

Therefore, after the 1st half-life, there is (190/2) g left; after the 2nd half-life, there is (190/2)/2 g left; so on and so forth.  After the 6th half-life, there is 190/(2*2*2*2*2*2) g = 190g/64 = 2.97 g left.

So 2.97 g of this radioactive isotope will be left after 6 half-lives.

Which of the following is NOT a trait of a morally good person? Ambitiousness

Explanation:

Charity (giving) is an essential trait. Choosing to help a person in need is a quality you would find in a moral person.

Being courageous (moral courage) and taking responsibility when needed is another quality.

Trustworthiness is a moral value and is considered to be a virtue.

Ambitiousness is not bad, but it is not necessarily a moral value. Ambition has to do with the desire of achieving success or a certain goal.
