Answer 1

Dear student,

Ionization of Na2SO4 is given as

Na2SO4 -----------> 2Na​​​+ + SO​​​​​4​​​​2-

From the above equation we may concluded that

1 mole of Na2SO4 gives 2 moles of Na+ ion .

2.5 mole of Na2SO4 gives 2 * 2.5 moles of Na+ ion.

Therefore,

Moles of Na+ ion = 2 * 2.5 mol

= 5 mol

Hence,

2.5 moles of Na2SO4 gives 5 moles of Na+ ion.

Please give positive rating to this answer.
