Given
1.58 moles of LiOH
Required
The number of formula units
Solution
The mole is the number of particles(molecules, atoms, ions, formula units) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
So for 1.58 moles :
= 1.58 x 6.02 x 10²³
= 9.5116 x 10²³
