Element x decays radioactively with a half life of 13 minutes. If there are 970 grams of element x, how long, to the nearest ten
Masteriza [31]

The time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.

<h3>What is half-life?</h3>

Half-life is the time half-time of the total decay of any element.

Given that, Initial amount  =  970 grams

Final amount =  98 grams

Half life =  13 minutes

To find the half life

Half life \times \dfrac{\dfrac{initial \;amount}{final\;amount} }{log2} \\\\\\13 \times \dfrac{\dfrac{970 }{98} }{log2} = 9.897

Thus, the time taken to the nearest tenth of a minute, would it take the element to decay to 98 grams is 9.897.
