Paragraaf 4 scheikunde
Relatieve atoommassa
Cl-35  75,5%
Cl-37  24,5%

u= atomaire massa eenheid

Molecuulmassa
Bereken de molecuul massa van glucose (C 6H12O6)
6 keer C  6 keer 12,01 = 72,06
12 keer H  12 keer 1,008 = 12,096
6 keer O  6 keer 16,00 = 96,00 +
--------------------------------------------------------------
180,156 u

De mol / de chemische hoeveelheid.
Vast aantal deeltjes

Van ‘u’ naar g/mol

1= Bereken de molecuulmassa, zonder eenheid
2= Als eenheid: gram / mol

Reken met Mol en massa

Bereken de chemische hoeveelheid van 6,5g glucose.
Chemische hoeveelheid = aantal mol
g 180,156 6,5

mol 1 A


A= 1 x 6,5 : 180,156 = 0,036 mol glucose

Bereken de massa van 8,2 mol glucose
g 180,156 B

mol 1 8,2


B= 8,2 x 180,156 : 1 = 1477 g
