How find molecular formula
WebHet aantal mol kan worden berekend met de formule: n=PV/RT. [2] In deze formule is n het aantal mol, P de druk, V het volume, T de temperatuur in Kelvin en R de gasconstante. Voorbeeld: n=PV/RT= (0,984 atm x 1 L) / (0,08206 L atm mol-1 K-1 x 318,15 K)=0,0377 mol 3 Bereken de molecuulmassa van het gas.
