E = MC2 I suppose...
well according to jayaxe, any formula might just do the trick..haha.. here are some of the actual formulas I have to remember...
PV = nRT
P1V1 = P2V2
Densities of gases directly proportional to M.R
Density = Mass / Volume
V = moles x 22.41 (at S.T.P) or 24.47 (at 25C)
PV / T is constant for any P,V or T
p (gas) = total P x volume fraction / p (gas) = nx / (nx +ny) x final Pressure
P1V1 / T1 = P2V2 / T2
pH = -log [H+]
[H+] = 10 -pH
Kw = [H+] [OH-]
