Question

ce cantitate de ocsijen se gaseste in 2 moli de h2so4

Answer 1

1 mol H2SO4 contine 6,023*10²³ molecule.Fiecare molecula contine 4 atomi de O , deci 1 mol H2SO4 contine 4*6,023*10²³=2,4092*10²⁴ atomi de O.

1 mol O=6,023*10²³ atomi

$Nr \ moli \ O \ ce \ se \ gasesc \ in \ 1 \ mol \ H_2SO_4=\frac{2,4092*10^{24}}{6,023*10^{23}}=4$

$In \ 2 \ moli \ de \ H_2SO_4 \ se \ gasesc \ 2*4=8 \ moli \ O$
