    The percentage of N in the compound is 0.5088

    Explanation:

    Mass of compound = 8.75 mg = 8.75*1000 = 8750 g

    Mass of N2 = number of moles of N2 * MW of N2 = 1.59 * 28 = 44.52 g

    % of N in the compound = (mass of N2/mass of compound) * 100 = (44.52/8750) * 100 = 5.088*10^-3 * 100 = 0.5088
