  1. 1 mole contains 1.02 x 10^23 molecules.

    Hence you can calculate the number of moles 1.02 x 10^24 molecules represents.

    If you calculate the mass in grams of one mole of NaCl from the atomic masses, you can find the answer.

  2. DrRuss made a typo above; he intended, I'm sure, to write 1 mol contains 6.02 x 10^23 molecules.
