The number of years it would take for radium to be 5 grams is 6967 years.
<h3>After how many years will only 5 grams of radium be present?</h3>
The formula that is used to represent continuous compounding or continuous decay is:
FV = A x x N
Where:
- A= amount
- e = 2.7182818
- N = number of years
- r = interest rate
5 = 100 x e^−0.00043 x t.
In order to determine the value of t, take the following steps:
Divide both sides by 100
5/100 = e^−0.00043 x t.
Then take the In of both sides
= 6967 years
