How do I make a 6M NaOH solution? (25mL)

Question

and is there a certain way to make NaCl saturated? or is it already saturated?

For molarity, remember the definition.
Molarity - # mols/L
# mols = grams/molar mass.

equation 1.
M=mols/L
6M = mols/0.025 L
mols = 6M x 0.025 L = ?? That is the # mols you need.

equation 2.
mols = g/molar mass
?? from above = g/molar mass.
Plug in molar mass NaOH and solve for grams. Dissolve that many grams in some water. After it is dissolved, make the final volume to 25 mL.

For NaCl, it is quite soluble. The way to make it is to dissolve NaCl until no more will dissolve. Then it is saturated. To help determine how much NaCl that is, you can look up the solubility of NaCl. That will give you an idea how much to weigh if you know the volume.
