Answer:
15 g
Step-by-step explanation:
Given,
Plutonium-244 = 30 g
We have to find the gram of Plutonium-244 left after 1 half-life.
We know that the half-life of a radioactive isotope is constant. The half-life of a Radioactive isotope does not depend on the initial amount of isotope.
Now,
After 1 half-life
Plutonium-244 left =
= 15 g
Hence, 15 g of the Plutonium-244 will be left after 1 half-life.
