The half-life of uranium-235 is 700,000,000 years. The half-life of uranium-238 is 4.463×1011 years longer. What is the half-life of uranium-238? The answer should be in decimal form.(1 point)
Responses
The half-life of uranium-238 can be found by adding the difference in half-life to that of uranium-235.
Half-life of uranium-235 = 700,000,000 years
Difference in half-life between uranium-238 and uranium-235 = 4.463×10^11 years
Half-life of uranium-238 = Half-life of uranium-235 + Difference in half-life
Half-life of uranium-238 = 700,000,000 + 4.463×10^11 years
Calculating the sum:
Half-life of uranium-238 ≈ 4.4641637 × 10^11 years
Therefore, the half-life of uranium-238 is approximately 4.464 × 10^11 years in decimal form.
