The number of units of NaOH are in 80 grams is 12.046 x 10²³ Particles of NaOH.
The mole, symbol mol, is the SI base unit of amount of substance.
The quantity amount of substance is a measure of how many elementary entities of a given substance are in an object or sample.
Formula to calculate number of Particles when weight of the sample is given ;
N = given weight / Molecular weight x Nₐ
= 80 / 40 x 6.023 x 10²³ Particles
= 12.046 x 10²³ Particles of NaOH
Hence, The number of units of NaOH are in 80 grams is 12.046 x 10²³ Particles of NaOH.
