Masa moleculara pentru H2O2= 2×1 + 2×16=34
Asadar 34 g H2O2.....2g de H
Amestecul contine 6 g H => 6-2 =4 g H in H2O
Masa moleculara pentru H2O= 2×1 + 16=18
Asadar 1 mol de H2O....2g H
x moli de H2O....4g H
x= 4/2= 2 moli H2O
In amestec avem 1 mol de H2O2 si 2 moli de H2O
p H2O= 2/3 ×100= 66,66%
p H2O2=1/3 ×100= 33,33%
