The ratio of molecular mass of two radio...

 The ratio of molecular mass of two radioactive substances is.`3//2` and the ratio oftheir decay constant is `4//3`. Find the ratio of their initial activity per mole.

Text Solution

Verified by Experts

Activity `R = lambdaN`
Number of nuclei (N) per mole are equal for both the substances
`therefore`   `Rproplambda` 
Or `(R_(1))/(R_(2))=(lambda_(1))/(lambda_(2))=(4)/(3)`
