The ideal gas law states that N = PV/RT (or whatever form you prefer) where:
N = moles
P = pressure
V = volume
R = 8.31 (UGC)
T = temperature

Please write the equation to solve for EACH variable, leaving five different equations. (ex: to solve for moles, N = PV/RT or to solve for for temp, T = PV/RN)

I know this is easy, i just have trouble doing simple sh!t like this. Help please?
 
it would be better if you rearrange it and have it memorized this way
PV = NRT
now if you wanna get P you divide everything by V, and if you want V u divide everyhtin by P same for the other side

so now you have

P=NRT/V

V=NRT/P

R=PV/NT

and by the wayyou don't use this value for R you use
R= .0821L*atm/K*mol because the units for this r have joles in it and we don't use joles in gas

hope that helped and made it easier for u :)
