Question

Calculati compozitia procentuală pentru: H2 SO4 ; H2 SO3 ; H2 O

Answer 1

MH2SO4P=2+32+64=98g/mol
98gH2SO4...2gH...32gS...64gO
100gH2SO4...x.........y...........z
x=100*2/98=2,04%H
y=100*32/98=32,65%S
z=100*64/98=65,30%O

MH2SO3=2+32+48=82g/mol
82gH2SO3...2gH...32gS...48gO
100gH2SO3....x........y...........z
x=100*2/82=2,43%H
y=100*32/82=39,02%S
z=100*48/82=58,53%O

MH2O=2+16=18g/mol
18gH2O...2gH...16gO
100gH2O...x........y
x=100*2/18=11,11%H
y=100*16/18=88,88%O
