The dead battery with a percentage composition of 70.0% Mn and 30.0% O has the empirical formula Mn₂O₃.
An empirical formula is the minimal relationship between the atoms in a chemical formula.
A dead alkaline battery is 70.0 % Mn and 30.0 % O. To find the empirical formula, we will divide each percentage by the molar mass of the element.
Then, we divide both numbers by the smallest one.
Finally, we multiply both numbers by 2 so that they are whole numbers.
