Question

Determinati masa moleculara a acidului sulfuric H2SO4

Answer 1

Formula moleculara acid sulfuric: H2SO4


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
