Question

Calculeaza:a)ce cantitate de S se gaseste in 10 moli SO2,b)masa de amoniac in care se gaseste 42gN?​

Answer 1

Răspuns:

Explicație:

a.

m = n . M

MSO2= 32 + 2.16= 64-----> 64g/moli

m= 10moli . 64=640g SO2

64g SO2------32gS

640g------------x

x= 640 . 32 : 64=320 g S

n= 320g : 32g/moli= 10 moli S

b.

MNH3= 14 +3= 17------> 17g/moli

17g NH3--------14g N

Xg NH3---------42g N

X= 17 . 42 : 14= 51 g NH3

n= 51g : 17g/moli= 3 moli NH3
