I'm from norway, and i i'm not sure if this is the right word, but i need help for a chemical balancing task.

"Chemical-K for I₂ when temperature is 1000 K is
K= 3,76 * 10^5

The reaction equation is I₂ ? 2I . In an experiment we started with 1,0 mol pure Iodine in a 2,00 dm³ box, and it is then warmed up to 1000K. How much "atomært" iodine was it in the box, when chemical balance is disposed.
I guess atomært means 2I. Sorry for the bad englsih, but it was hard to write chemistry from norwegian to english, a lot of hard words.

Please help me, i'm confused.

At first, you should write the reaction. Thus, you calculate the molarity concentration of I₂. You take "x" as the concentration of I₂ which I₂ reacted and use K. That's all
