given data:moles of H2=0.001mole , given weight of the unknown metal(M)=0.0757 ggiven equation:M(s)+nH30^+1........>M^(+n)+ (n/2) H2 + nH2Ofrom the stoichiometry of the reaction and the number of moles of H2 given,calculate the number of moles of metal in the sample.Assume that n in the balanced equation for the reaction is either 2 or 3.From the weight of the sample,then determine the two possible atomic masses of metals.Consult the periodic table to see which more nearly corresponds to a known metallic element.
