Question

Ce compozitie procentuala are H2S (acidul sulfhidric) si H2SO4( acidul sulfuric)?

Answer 1

34g H2S........2g(H)............32g(S)
100gH2S.......x%(H)............y%(S)
x=(100 ori 2):34=5,88%
y=(100 ori 32):34=94,12%
  
Mh2so4=2 x 1 +32 + 16 x 4=98
 
98g H2SO4........2g(H).......32g(S)......64g(O)
100gH2SO4.......x%H..........y%S.........z%O
x=(100 ori 2 ):98=2,04 % H
y=(100 ori 32):98=32,65 % S
z=(100 ori 64):98=65,30 % O
