Why is it not possible to use solid sodium hydroxide directly to make a standard solution?

Solid sodium hydroxide is deliquescent (absorbs moisture from the surrounding air). As a result, if you tried to weigh a certain amount of NaOH to create a standard solution, the actual mass of the pure NaOH will be different from the mass of the NaOH you weighed, so you cannot really produce the standard concentration you need.
