Question

The disinfectant hydrogen peroxide (H2O2)
decomposes to form water and oxygen gas.
How much O2 will result from the decomposition of 5.94 mol of hydrogen peroxide?
2H2O2 ==> 2H2O + O2
5.94 mols H2O2 x (1 mol O2/2 mols H2O2) = 5.94 x 1/2 = ? mols O2
If you want grams that is g = mols x molar mass = ?
If you want volume @ STP that is volume = mols O2 x 22.4 L/mol = ?
