Answer:
The correct answer is beta decay
Explanation:
When a beta particle is emitted from a radioactive atom,at that time the daughter atom that is produced have atomic mass 1 unit more than that of its parental atom.
In the given reaction a beta particle is emitted from the carbon atom resulting in the formation nitrogen atom,The atomic mass of nitrogen atom is 7dalton which is one unit more than the atomic mass of carbon that is 6 dalton.
First you would multiply 5,3, and 2 to get a volume of 30. Density is mass over volume so you would then divide 129 by 30. You would get 4.3. The answer would be 4.3 g/cm^3
