Scientist are studying an 500g. Sample of a radioactive element. Which has an annual decay rate of 11%. How many grams of the sa
gtnhenbr [62]

Nothing

Explanation:

Mass of the sample = 500g

Decay rate per anum = 11%

Unknown:

Mass of sample remaining after 10yrs = ?

Solution:

  This is a simple percentages problem;

The radioactive sample loses \frac{11}{100 } x 500g of sample per year;

  this is a loss of 55g per year;

In 10years time, the sample would have lost 10 x 55g = 550g of element.

Since our sample is not up to 550g, then no amount of sample will remain after 10yrs.
