I've been seeing multiple formulas for converting kp to kc - are these just multiple forms of a single formula? Or is there a universal formula for converting kp to kc in any given problem?

The ideal gas law should be your go to:
PV=nRT

Will we need to convert from Kc to Kp for this test?

There's also an equation that goes from Kc to Kp
Kp=Kc(RT)^delta(n) or Kp=(T/12.03)^delta(n)*Kc

you will want to use the formula PV=nRT. if you just move the V to the other side you get P=nRT/v. But n/v is just concentration. So you replace n/v with your concentration for kc then you plug in your T and R constant to get P.
