Question

A radioactive compound with mass 470 grams decays at a rate of 3% per hour. Which

Answer 1

After 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.

What is exponential decay?

During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.

We know the decay can be as:

$\rm C = a(1-r)^t$

We have:

a = 470 grams

r = 3% = 0.03

t = 6 hours

$\rm C = 470(1-0.03)^6$

C = 391.49 grams

Thus, after 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.
