Răspuns:
0,56kg=56g
A Fe= 56g/mol Z =26 ==>26e⁻ in invelisul electronic
1 Kmol Fe=56kg
-in 56g Fe....... 6,023x10²³ atomi Fe.........56x6,023x10²³e⁻
560gFe..........................................................x=calculeaza
A C=12g/mol
Z C=6 → 6e⁻
12gC contin 6,023x10²³ atomi C........6x6,023x10²³e⁻
120gC.................................................y=calculeaza
