Explicație:
5moli SO3
nr. molecule
m=80g CO
VCO
=====>
1mol SO3------------6,022 .10²³molecule SO3
5moli SO3---------------------x
x= 5 . 6,022.10²³ = 30,11 . 10²³ molecule SO3
=======>
n= m : M
MCO= 12 + 16=28-------> 28g/moli
n= 80g : 28g/moli =2,86 moli CO
VCO= 2,86moli . 22,4 L/moli=
calculeaza !!!!!!!
