Answer:
= 1/4
Step-by-step explanation:
- Half life refers to the time taken by a radioactive isotope or atom to decay by half of its original mass.
Using the formula;
N = O × (1/2)^t;
Where N is the new mass after decay, while O is the original mass of the radioactive isotope before decay, while t is the number of half lives.
Therefore;
Number of half lives = 11, 460/5730 = 2 half lives
Thus;
New fraction = 1 × (1/2)²
= 1/4
Therefore, the fraction that will remain after decay is 1/4 of carbon-14.
