Q

mu = ?

A

1,661 . 10^-23 g
het is de referentie, dit getal is eigenlijk de massa van 1 proton. Het maakt het vergelijken en opschrijven van atoommassa’s eenvoudiger (omdat het gewicht van atomen mega klein is)

Q

massa van stof in gram

A

Mr(x)= m(x)/ n(x) of n(x) = m(x)/ M(x)

Mr(x) = relatieve molecuulmassa in g/ mol
n(x) = aantal mol
m(x)= massa van de stof in gram

Q

Molaire gasdruk

A

pm= p/ n = V.T/ n (= druk uitgeoefend door 1 mol gasdeeltjes)

p= druk in de gas
n= aantal deeltjes
pm bij norm omstandigheden = 2270 Pa/ mol
