Question

calculati compozitia procentuala a HCL si H2so4.

Answer 1

M HCl= 1+ 35,5= 36,5g/mol
In 36,5 g HCL...............35,5 g Cl............1g H
   100g HCl.....................x g Cl.................y g H
x= 100*35,5 / 36,5=97,26% Cl
 y= 100*1 / 36,5=  2,73% H

M H2SO4= 2*1+32+4*16=98g/mol
In 98g H2SO4................2*1=2 g H.............32g S..............4*16= 64 g O
   100g H2SO4...............x g H......................y gS................z g O
x=100*2 / 98= 2,04% H
y=100*32 / 98= 32,65% S
z= 100*64 / 98= 65,30% O
