Answer: molar mass of H2O2 = 34 g/mol
mass of H2O2 = 68 grams
Explanation:
The decomposition reaction of Hydrogen peroxide (H2O2) is:
2 H2O2 → 2 H2O + O
According to the equation the numbers of moles of H2O2 is 2 moles.
The molar mass of H2O2 = ( 16×2) + (1x2)
32 + 2 = 34 g/mol
∵ atomic mass of oxygen is 16 and hydrogen is 1.
Now, mole=[tex]\frac{mass-in-gram }{molar mass}[/tex]
putting values
2=[tex]\frac{mass}{34}[/tex]
mass of H2O2 = 2 × 34 = 68 grams
