a.
n= 179,2L : 22,4 L/moli= 8moli CO
1molCO-------------6,022.10²³ molecule CO
8moli ---------------------------x
x= 8 . 6,022.10²³ molecule =48,176 molecule CO
b.
n= 112,5L : 22,4L/moli=5moli NO2
m= n .M
MNO2= 14 + 2.16=46-----> 46g/moli
m= 5moli. 46g/moli= 230g NO2
c.
VCO2= 0,25moli . 22,4L/moli=5,6 L
