Răspuns:
atomul are 16e=16p si n= 32-16=16
1molS............ARE 32g............N,A= 6,023X10²³ atomi........informatii
a)32g...............N,Aatomi (numarul lui Avogadro)
2g...................x= 2N,A/32atomi
1atom....................16p
2N,A/32................x=N,Aprotoni= 6,023x10²³ protoni
b) 1molS..........N,Aatomi.
0,5mol............x= 0,5N,A atomi
1 atomi.............16e
0,5N,A....................x=N=0,5X16X6,023X10²³e=48x10²³ e
