Number of mols present at equilibrium?

At a certain temperature, the equilibrium constant for the following chemical equation is 2.90.

SO2(g)+NO2(g)⇌SO3(g)+NO(g)

At this temperature, calculate the number of moles of NO2(g) that must be added to 2.42 mol of SO2(g) in order to form 1.10 mol of SO3(g) at equilibrium.

I got 0.784 mol, but it was wrong. I really don't think I understand the concept. If someone could help me out, it would be greatly appreciated!
