    Mass of 1 atom of C-14 = 14 a.m.u.

    Mass of 1 mole of C-14 = 14 grams

    <hr />

    (using unitary method)

    14 grams = 1 mole

    Therefore, 7 grams = 0.5 mole

    <hr />

    1 atom of C-14 has 8 neutrons

    0.5 mole of C-14 has 8 * NA = 8 * 6.022 * 1023 = 4.8176 * 1024  neutrons
