How many atoms of `0.1 g`-atom of a radioacitve isotope `._(Z)X^(A)` (half life = 5 days) will decay during the 11th day?

A

`0.1(-e^(-(0.693xx11)/5)+e^(-(0.693xx10)/5))`

B

`0.1(-e^((0.693xx11)/5)+e^((0.693xx10)/5))`

C

`0.1(-e^(-(0.693xx11)/5)+e^(-(0.693xx10)/5))N_(A)`

D

`0.1(-e^((0.693xx11)/5)+e^((0.693xx10)/5))N_(A)`
