firstly we will calculate the no. of protons and neutrons as both are same in this case.
formula for finding the no. of particles is
no. of moles = total no. of entities /6.022×10^23
now it is given that sample has 5 mole of O^-2 anion , also O contains 8 protons and neutrons, putting it in formula we get
8×5×6.022 ×10^23= 2.4 ×10^25
now we have to calculate the no. of electrons
so as we know that O^-2 contains 10 electrons per atom , repeating the step we get 10×5×6.022×10^23
please do the calculation of second part yourself.
