H=1/1= 1 mol H ||:0,5 => 2 atomi H
S=16/32=0,5 moli S ||:0,5 => 1 atom S
O=32/16=2 moli O ||:0,5 => 4 atomi O
F.M => H2SO4
H2SO4 + M => MSO4 + H2
Mg...................................22,4 L H2
6,5g.................................2,24 L H2
2,24M=145,6 => M=65, metalul corespunzator este Zincul, M=65g/mol
c. 98g H2SO4........................22,4 L H2
x g H2SO4............................2,24 L H2
x=98*2,24/22,4=9,8g H2SO4 (md)
C=md/ms*100=>ms=md*100/C=9,8*100/49=980/49 =
MH2SO4=98g/mol
