Determinati masa moleculara a acidului sulfuric H₂SO₄

Formula moleculara acid sulfuric: H₂SO₄

Rezolvare

Moleculele de H₂SO₄ contin:

2 atomi de Hidrogen (H), 1 atom de Sulf (S), 4 atomi de Oxigen (O)

2 atomi de hidrogen (H) ∙ 1,008 g / mol = 2,016 g / mol

1 atom de sulf (S) ∙ 32,066 g / mol         = 32,066 g / mol

4 atomi de oxigen (O) ∙ 15,999 g / mol   = 63,996 g / mol

TOTAL……………………………….. = 98,078 g / mol
