  • chem - ,

    3 mg F x (1 g/1000 mg) x (1 mol F/19.0g F) x (1 mol NaF/1 mol F) x (42 g NaF/1 mol NaF) = xx
    Check my thinking and look carefully at each term I've used. I initially inverted some of them.

  • chem - ,

    The answer above is in grams. You will need to convert it to mg. Also, check the atomic and molar masses.
