Helloo!!

1 mole of sodium sulphate contains = 6.022×10^23 molecules 
0.1 mole = 0.1×6.022×10^23 = 0.6023×10^23 molecules
1 molecule of Sodium sulphate  contains 2 ions of Na
Therefore , 0.1 mole of sodium sulphate contains = 2 ×0.6023×10^23   = 1.2046 ×10^23  ions.
Number of sulphate ions = 1 x 0.6023×10^23  = 0.6023×10^23 ions

hope it helps!!

Sodium ions =14.2×2/(23+32+64) ×6.022×10^23
=1.437×10^23 ions
