The half — life of nickel is 96 years. How much of a 30-gram sample is left after 270 years?
-Dominant- [34]

The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams

<h3>How to determine the number of half-lives </h3>

We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:

  • Half-life (t½) = 96 years
  • Time (t) = 270 years
  • Number of half-lives (n) =?

n = t / t½

n = 270 / 99

n = 2.8125

<h3>How to determine the amount remaining </h3>
  • Original amount (N₀) = 30 grams
  • Number of half-lives (n) = 2.8125
  • Amount remaining (N) =?

The amount remaing can be obtained as follow:

N = N₀ / 2^n

N = 30 / 2^2.8125

N = 6.61 grams
