You can start by obtaining the molar mass of Na2S2O3 in conjunction get the molar masses of Na2, S2 and O3. DIVIDE the individual masses BY the molar mass of the molecule Na2S2O3 and MULTIPLY by 100 each to obtain the percentage mass of each element in the molecule. If it matches the original percentual analysis, then you're done.
