Is the answer D. 1?
I got this by:
...........NaCl.................................................................Na2 SO4
1mole Cl <---> 1 mole Cl..................................2mole Na<---> 1 mole SO4
0.6mole Cl -> 0.6 mole Na....................................0.2mole SO4 <---> 0.4mole Na.
0.6 + 0.4 = 1.0mole of Na? Am i right, that's how my teacher told me how to do a question like that as I got stuck on a similar one.
