    The percent composition of each element can be calculated as follows:

    % composition = (mass of element / total mass) * 100

    The total mass of the quarter is given to be 5.670 grams

    Mass of Cu = 5.198 grams

    Mass of Ni = 0.472 grams

    Substitute in the above equation to get the mass percentage of each element as follows:

    % of Cu = (5.198/5.670) * 100 = 91.675%

    % of Ni = (0.472/5.670) * 100 = 8.325%
