Ten grams of `^57 Co` kept in an open container beta-decays with a half-life of 270 days. The weight of the material inside the container after 540 days will be very nearly

A

`10 g`

B

`7.5 g`

C

`5 g`

D

`2.5 g`

Text Solution

Verified by Experts

The correct Answer is:
A

The weight will not change appreciable as the process is `beta`-decay.
