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...
