The activity of radionuclide (""^(100)X)...

The activity of radionuclide `(""^(100)X)` is 6.023 curie. If the disintegration constatnt is `3.7xx10""^(4)sec""^(-1)`,the mass of radionuclide is

A

`10""^(-14)`g

B

`10""^(-6)`g

C

`10""^(-15)`g

D

`10""^(-3)`g

Text Solution

Verified by Experts

The correct Answer is:
c
Rate=`lamdaN=(lamdaxx"Av.no"xxmass)/(At.mass)`
`3.7xx10""^(10)xx6.023=(3.7xx10""^(4)xx6.023xx10""^(23)xxa)/100`
`therefore` a=`10""_(g)""^(-15)`
