Sodium hydroxide weighs 40 g per mole and provides only one OH- per mole.
Thus 40 g in 1 litre is 1 normal.
5 N would be 200 g in 1 litre of total solution. Add enough water to 200 g
of sodium hydroxide to reach almost to the 1 litre mark. Dissolve and add
enough water to reach the 1 litre mark.  Note that 5 N sodium hydroxide eats
flesh.  Keep it off your hands !  2N sodium hydroxide would be 80 g in 1
litre of total solution.
