Expert Answer:

Dear student,
Number of neutrons can be calculated by-
number of neutrons=Atomic mass number(A)-Atomic number(Z)
                             =(number of protons +number of neutrons)- (number of protons)
It is not posssible to calculate number of neutrons without knowing atomic number and atomic mass number.
