Suppose the half life of an isotope is 30 seconds and you have 10 grams to start with how much will you have after one minute

Hello!

The half-life is the time of half-disintegration, it is the time in which half of the atoms of an isotope disintegrate.

We have the following data:

mo (initial mass) = 10 g

m (final mass after time T) = ? (in g)

x (number of periods elapsed) = ?

P (Half-life) = 30 seconds

T (Elapsed time for sample reduction) = 1 minute → 60 seconds

Let's find the number of periods elapsed (x), let us see:

Now, let's find the final mass (m) of this isotope after the elapsed time, let's see:

I Hope this helps, greetings ... DexteR! =)
