Question

va rog sa rezolvati problema dau coroana!!! Numarul de electroni care se afla intru-un mol de dioxid de sulf este...a) 32*6,023*10 la puterea 23 electroni b) 3,2*6, 023*10 la puterea 24 c) 16*6,023*10 la puterea 23 electroni​

Answer 1

SO2, S are Z= 16 (16 e-) si O are Z= 8 (8 e-)

In total avem 16+2×8 = 32 e-

1 mol ..................... 32×6,022×10la23

=> 1,927×10la25 e-
