# Simple question about C of a solution

suppose that the molar concentration of (2k+ , (S2O4)2-) is C=1mol/l

we have C((S2O4)2-)=C=1mol.l but does C(2k+)=1 mol/l ? or 2C=2mol/l(since there are 2 k+ )

this question might be silly , but this really confused me and i can't come up with the correct answer

2 mol/L.
