Question

What percentage of a radioactive species would be found as daughter material after five half-lives?

Answer 1

Answer:

i believe the answer is e on plato

Step-by-step explanation:

Answer 2

The answer is 3.125%.

The relation between number of half-lives (n) and amount of sample that remained (x) can be expressed as:
$(1/2)^{n} =x$

It is given:
n = 5

To find x, we will change n in the equation with five:

$(1/2)^{n} =x$
⇒ $(1/2)^{5} =x$
⇒ $0.5^{5} =x$
⇒ $x=0.03125 = \frac{3.125}{100} = 3.125%$

Therefore, 3.125% of a radioactive species would be found as daughter material after five half-lives.
