Below is the solution: n equation showing conservation of mass of reactants and products:  2H2O --> 2H2 & O2  what is the mass of the oxygen gas produced, from 178.8 g H2O , (using molar masses:  178.8 g H2O @ (1mol O2)(@ 32.00 g/mol) / (2molH2O)(18.02g/mol) =  your answer (4 sigfigs): 158.8 g O2  178.8 g H2O ---> 20.0 H2 & 158.8 O2
