In 3000 K the constant of disintegration in the equilibrum of the reaction Cl2-> ( <-) 2Cl is 0.570 atm.In the equilibrum the reaction weighs 3 miligrams and is contained in a dish with volume 60 mL and the temperature is 3000 K.Find the total pressure.

So I used p=n/V*R*T where n=m/M when M is the molar mass =34 ( since the molar mass of Cl is 17, 17*2=34). And R=0.08
Then I did Cl 2Cl
First (p1 I found) 0

Change -x 2x
Equilibrum p1-x 2x

Here by the constant of equilibrum I tried to find x ...am i right?
1. The problem statement, all variables and given/known data



2. Relevant equations



3. The attempt at a solution

Not easy to follow what you wrote, but I don't see anything that would in an obvious way suggest you are wrong.

For sure you should not round down all these numbers so heavily, as the answer you will get will be off. Round down only the final answer.
