Fie 100g solutie.
Aplicam formula concentratiei si scoatem md.
md=C×ms/100=20g×100g/100=20g H2SO4
Acum aplicam denistatea
ro=m/V de unde scoatem V=m/ro=20g/1.14g/cm3=17.54 cm3
Acum aflam nr de moli ca sa inlocuim in concentratia molara.
n=m/M=20g/98g/mol=0.204moli
Acum inlocuim in concentratia molara
17.54cm3=0.01754l
C=n/Vs =0.204moli/0.01754l=11.63 M
