Because they are different elements have different number of protons and neutrons........ I guessed do not trust me...
Answer:
Photodisintegration!
Explanation:
also called Phototransmutation, in physics, nuclear reaction in which the absorption of high-energy electromagnetic radiation (a gamma-ray photon) causes the absorbing nucleus to change to another species by ejecting a subatomic particle, such as a proton, neutron, or alpha particle.
The mass can be obtained from the molar mass when the number of moles is known.
<h3>What is molecular formular?</h3>
The molecular formlar is the formula of the compound that shows the number of atoms of each element that is present in the molecule. Asprin is a moecule that has the molecular formula C9H8O4.
To use the molecular formula to determine weight, we have to know the number of moles involved.
Mass = number of moles * molar mass.
