For the system, H2(g)+X2(g) <> 2HX(g) Kc=24.4 at 300K. A system was charged with 1 mole of H2 and 1 mole of I2 in a 3 liter container. The catalyst was introduced using a remote unit, and the system was allowed to come to equilibrium. How many moles of H2 will be present when the system reaches equilibrium?

You have the equation.
Convert 1 mol to molarity. 1 mole/3 liters.
Set up an ICE chart, plug in the numbers and solve for the unknown. Subtract from 1/3 to find how much H2 remains after equilibrium is established, then multiply by 3 L to find moles H2.
