    Cool, chemistry homework. There's some things lacking from you question that you need to find.

    1) What is the molar mass of NaCl. The molar mass is the mass of the substance that contains Avogadro's number of molecules. The number you'll find will say like XX g/mole.

    2) You need to specify the units of mass. You have -0.0001, that needs to be greater than zero and include the units of mass. Maybe 0.0001 grams (g)? You need to make sure you have consistent units between the molecular weight and the mass you have.

    Try to figure these things out and show what you tried.
