Explicație:
10moli HCl
MHCl= 1+ 35,5=36,5------> 36,5g/moli
m=n .M
m=10moli. 36,5g/moli=365g HCl
56g CO
VCO
MCO=12+16=28------->28g/moli
n=m:M
n= 56g: 28g/moli=2moli CO
VCO=2moli . 22,4L/moli=44,8 L
34g NH3
nr. atomi
-in molecula NH3 se afla 4atomi [ 1N+3H]
MNH3=14 +3=17------->17g/moli
n=34g : 17g/moli=2moli NH3
1mol NH3---------4 . 6,023.10²³atomi
2moli------------------x
x=2 .4 .6,023.10²³atomi=48,184.10²³atomi
