Help Me with Chem Real Quick

On the planet Quazzal, the mole fraction of carbon monoxide is .6271. The standard atmospheric pressure on Quazzal is 13.0atm. Determine the partial pressure of carbon monoxide on Quazzal.

 

I, uh, sort of forgot how to get mole fractions with only the standard pressure. Help me out?

 

Is it just a proportion like:

 

.6271       x atm

-------- = ---------

  1.0      13.0atm

 

Or am I missing something?

Oh! Is it 13.0=x(.6271) ? And x is the partial pressure?

[byalexandr]

Got it, I think it's 8.1523 atm.
