Wt. of ion= 32*4+16*6=224
There is 1/10 moles of ion.
1 ion has 16*4+8*6+2=114
there is 114/10=11.4 moles of electron .....
DUDE..

weight of s₄o₆^2-=224=1 mole
bt the given weight is 2.24 gm
therefore, no. of moles=given weight/molecular weight
=2.24/224
=1/100 moles
1 ion has 114 elctrons
therefore, total no. of electrons=114/100=1.14 moles of electron
