## Question

### Solution

Correct option is

4.20 g

The decay constant of polonium is

= 0.00502 day–1

If N0 be the number of atoms, or amount of radioactive substance, initially (at t = 0), then the amount left after time t is given by

Here   N0 = 5.00 g and t = one year = 365 days.

.

amount of polonium decayed is
