Protons-27
Electrons-21
Neutrons-32 (According to google), but 34 according to your set of numbers.
First, calculate the mass of sodium in g with the help of molar mass and number of moles.
Number of moles =
(1)
Molar mass of sodium =
Substitute the given value of number of moles and molar mass of sodium in formula (1)
(1)
(1)
mass of sodium in g = 
Now, according to conversion factor, 1 g = 1000 mg
So,
of sodium =
=
of sodium
Thus, mass of sodium in mg =
