17.9 moles of NaOH in 500 ml of water? please tell me the answer

I will be happy to critique your work.

See your earlier post.

To calculate the answer, we need to use the equation:

Moles (mol) = Molarity (M) × Volume (L)

First, we need to convert the volume from milliliters (mL) to liters (L).

500 mL = 0.5 L

Now we can substitute the values into the equation:

Moles (mol) = Molarity (M) × Volume (L)

To find the answer, we need the molarity of the NaOH solution. Please provide the molarity value, and I will be able to calculate the number of moles of NaOH.
