Chemistry, please help! I keep getting the wrong answer! Due at midnight?

The net ionic equation for the reaction :
2Cr²⁺(aq) + Cu²⁺(aq) → 2Cr³⁺(aq) + Cu(s)
SO₄²⁻ ions do not take place in the reaction.
Therefore, the concentration of SO₄²⁻ ions is unchanged during the reaction.

Molar mass of CuSO₄ = (63.5 + 32.1 + 16.0×4) g/mol = 159.6 g/mol
Initial no. of moles of CuSO₄ = (60.8 g) / (159.6 g/mol) = 0.381 mol

1 mole of CuSO₄ dissociates to give 1 mole of SO₄²⁻ ions.
No. of moles of SO₄²⁻ ions in the solution = Initial no. of moles of CuSO₄ = 0.381 mol
Volume of the solution = 245 mL = 0.245 L

Molar concentration of SO₄²⁻ ions in the solution = (0.381 mol) / (0.245 L) = 1.56 M

2 Cr(NO3)2 + CuSO4 → Cu + 2 Cr{3+} + 4 NO3{-} + SO4{2-}
The reaction described is entirely bogus -- it doesn't happen like that.
However the question can still be answered because the SO4{2-} ions don't participate in the supposed reaction anyway -- they are spectator ions.

(60.8 g CuSO4) / (159.6086 g CuSO4/mol) x (1 mol SO4{2-} / 1 mol CuSO4) / (0.245 L) =
1.55 mol/L SO4{2-} = 1.55 M SO4{2-}
