How many neutrons are in the nucleus of an atom with an atomic number of 25
(use periodic table for mass)

The neutron is 30

Explanation:

The element with atomic number of 25 is Manganese. it has a mass number of approximately 55.

Therefore, the neutron number = Mass number - Proton number (i.e. atomic number)

                                         = 55 - 25

  Neutron number            = 30

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
