write the balanced equation:
2H2O2>>2H2O + O2
how many moles of H2O2 is in 3.4 g?
molesH2O2=3.4/34=.1moles
so with the mole ratio in the balanced equation, you get half that of O2, or .05 moles O2
2H2O2>>2H2O + O2
how many moles of H2O2 is in 3.4 g?
molesH2O2=3.4/34=.1moles
so with the mole ratio in the balanced equation, you get half that of O2, or .05 moles O2

2H2O2 ==> 2H2O + O2
How many moles do you have in 3.4 g H2O2?
3.4/molar mass H2O2 = approximately 0.1.
You get 1 mol O2 for every 2 mol H2O2.
To convert to molecules, remember that there are 6.02E23 molecules in 1.0 mol.
