Respuesta :
The mass number of an atom which is made up of 27 protons,33 neutrons and 27 electrons will be 60.
What is mass number ?
The mass number of a particular atom is calculated by adding the number of protons and neutrons.
Calculation of mass number
It is given that,
Number of proton = 27
Number pf neutron = 33
Number of electron = 27
Mass number can be calculated by using the formula:
Mass number = number of proton + number of neutron
Mass number = 27 + 33
Mass number = 60
Therefore, the mass number will be 60.
