1
Q
number of particles = Nx L
A
where
n = amount of moles
L = Avogadro’s number 6.02x10^23
2
Q
n = m/M
A
where
n = amount of moles
m = mass (g)
M = RFM (molar mass)
3
Q
n = c x v
A
where
n = moles
c = conc
v = vol
4
Q
n = Vgas /24
A
n = moles
Vgas = gas volume (dm3)
24 = molar volume of a gas at rtp
