Another routine bookkeeping question.Since you are going from mole based units to g, you will need to use the molar mass.

Amount (moles) = volume (L) x concentration (M)

Not a difficult calculation in this case.

To go from that number of moles to g, multiply by molar mass; that is what it means.

Finally, since the solution is only 50%NaOH, divide your answer by 50% or 0.50

That's all.  Over to you.
