Question

Calculati compozitia procentuala a Hgo(oxid de mercur),raportul atomic ,raport masic.

Answer 1

Răspuns:

Explicație:

HgO

raport atomic = r.a.

r.a.=1 Hg : 1O= 1 : 1

raport de masa = r.m.

r.m.= AHg : AO= 201 : 16

Compozitie procentuala prin masa moleculara

MHgO=201 +16=217------>217g/moli

217 g HgO--------201 g Hg-----------16 g O

100 g----------------xg--------------------------yg

x=100.201 :217=

y=100.16 : 217=
