If a sample originally had 120 Adams of carbon 14 how many atoms will remain after 17,190 years
adelina 88 [10]

Answer:

15 atoms

Explanation:

About 15 atoms out of the 120 Adams would remain.

<em>Generally, the half-life of a substance is the time it takes for one-half of that substance to disintegrate.</em>

Carbon 14 has a half-life of approximately 5,730 years. 17,190 years means that the sample had stayed for 17,190/5,730 which is equal to 3 carbon-14 half-lives.

Out of 120 Adams,

  • <em>the first half-life will reduce 120 to 60 Adams</em>
  • <em>the second half-life will reduce 60 Adams to 30 Adams</em>
  • <em>the third half-life will reduce 30 Adams to 15 Adams.</em>

<em>Hence, at the end of the 17,190 years, approximately </em><em>15 Adams</em><em> would remain.</em>
