How do I find the molarity of NaOH?

Molarity is the number of moles of solute dissolved in one liter of solution. So for example, if the molarity was 1, it would be 1 mole of NaOH per Liter. 1 mole of NaOH is 39.9g

Chris is right. Find moles using the molar masses. Take the number of moles and divide the number of liters. This gives you molarity.
Anyone you is giving you a molarity is wrong. NaOH(aq) is all you gave us, we need more info to answer your question. Just look at your problem and see how much stuff you have, how many grams? how many liters? were you given moles?
I just standardized a solution of NaOH for some analytical work a few days ago. You need grams (or moles) of NaOH, and you need liters of solution. Without those two, or some numbers that can lead you to those two you can't get a molarity.

Molarity, M is equal to Moles/ Liters.
Try taking the number of grams of NaOH and divide by the molecular weight (40.01 Grams per mole). This gives you moles. Then divide this by total volume of solution, in liters.

How To Find Molarity

its moles of solute over moles of solution. Use the mole hill if you mean somthing else. Remember multiply while going down.
Moles at the top
mult the forumula mass to find the mass
mlt by avagadros numer 6.04 x 10^22 or was it 24? to find the num of atoms
mult by 22.4 to find liters.
YAY

I THINK you and up each elements atomic mass and multiply by the number that defines molarity which i believe is 6.22 to the 23rd power

you divide the number of moles of NaOH you have in the solution by the liters of solution you have
that gives you moles/Liter, with is how molarity is defined

Sometimes I liked chem class.
