Question

cate grame de sulf se gasesc în 120g acid sulfuric 120acid sulfuros, 120acid sulfhidric .Vă rog am nevoie urgent..

Answer 1

H2SO4 acid sulfuric
masa atomica M=98 g/mol
daca in 98 g H2SO4 sunt 32 g Sulf
         in 120 g...................x g Sulf
                          x=39,18
H2SO3 acid sulfuric
M=82 g/mol
in 82 g... 32 g Sulf
in 120 g....y g Sulf
y=46,82
H2S acid sulfhidric
M=34 g/mol
in 34 g...32 g Sulf
in 120...z g sulf
z=112,94
