​

Answer 1

Answer:

If you like my answer mark as brainlist

Explanation:

The correct option is A.

Given,

Mass of radioactive element is m gram and the mass number is A.

The number of nuclei in a element of mass number A is 6.02×10

23

.

So, the number of nuclei in a element of having mass 1 gram is

A

6.02×10

23

.

Therefore,the number of nuclei of having mass m gram is

A

6.02.m×10

23

.

Answer 2

Answer:

The number of nuclei present in a mass m gram of radioactive element of mass number A is 6.02× 10 power to 23 m/A
