avogadros constant symbol
NA
avogadros constant unit
particles mol -1
what is avogardos constant
6.02 X 10^23 particles, each mole contains this many particles
to convert to the number of moles to the number of particles
multiply by avogardos constant 6.02 x 10^23
to convert to the number of particles to number of moles
divide by by avogardos constant 6.02 x 10^23
equation for calculating number of particles with known number of moles
