    The answer to this question would be: 14g of Carbon

    In this question, you are given the weight of the element. Then, to find the number of atoms you need to divide the weight with the molecular mass of the each element.

    14 g c / (12 g/mole) = 1.167 mole

    102 g ag / (107 g/mole) = 0.95 mole

    49 g cr / (52 g/mole) = 0.94 mole

    202 g pb / (207 g/mole) = 0.975 mole
