    A toothpaste contains 0.24% by mass of sodium fluoride used to prevent caries (cavities) and 0.30% by mass of triclosan (C12H7Cl3O2). A PRESERVATIVE + ANTIGINVITIS AGENT.
    a) How many moles of NaF are in a tube of toothpaste
    b) How many moles of F- are in a tube?
    c) How many grams of Na+ are in 1.50g of toothpaste?
    d) How many molecules of triclosan are in a tube of toothpaste?

    Note that the tube of toothpaste is equal to 119g.
