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 210 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.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
