A 2.000g sample of silver alloy was dissolved in nitric acid and then precipitated as AgBr. After drying, the sample of silver bromide weighed 2.000g. Calculate the percentage of silver in the alloy.

  • chemistry -

    moles AgBr = grams/molar mass.
    moles Ag = same since there is 1 Ag in 1 AgBr.
    grams Ag = moles Ag x molar mass Ag

    %Ag = (mass Ag/mass sample)*100 = ??
