A sample weighing 2.198 g containing a mixture of AO and A_(2)O_(3) takes 0.015 "mole of" K_(2)Cr_(2)O_(7) to oxidise the sample completely to form AO_(4)^(-) and Cr^(3+) . If 0.0187 "mole of" AO_(4)^(-) is formed, what is at.wt . of A ?

An element A in a compound ABD has oxidation number A^(n-) . It is oxidised by Cr_(2)O_(7)^(2-) in acid medium. In the experiment 1.68xx10^(-3) moles of K_(2)Cr_(2)O_(7) were used for 3.26xx10^(-3) moles of ABD . The new oxidation number of A after oxidation is:
