The Radioactive element americium-241 has a half-life of 432 years. Suppose we start with a 45-g mass of americim-241. How much will be left after 329 years? compute the answer to three significant digits.

Radioactive decay problems are modeled using an exponential function,
where N0 is the initial amount of material, k is a constant for each material.
Half life means that 1/2 of the initial amount remains.
We use this to calculate k.

.
So now find N(329).
