  1. M = mols/L
    moles = g/molar mass.
    Post your work if you get stuck.

  2. Molarity (M) = moles of solute / liters of solution
    2M = moles of NaOH / 1.0 L solution
    *Multiply both sides by 1.0 to get moles of NaOH
    Moles of NaOH = 2 moles
    2 moles NaOH 39.99 g NaOH / 1 mol NaOH
    Grams NaOH = 79.98 g (not counting sig figs)
    I don't know if this is correct but...
