A 25 mL sample of 0.100 M HNO3 completely reacts with NaOH according to this equation:
ASHA 777 [7]
To solve this equation you can use a basic molarity formula and substitute the correct values.

The formula for molarity is M = mol/L.

Start by changing your mL to L. To do this, divide 25 by 1000.
This results in:
.025 L

You can now rearrange your molarity formula to isolate what you are solving for, which is moles.
This leaves your formula as:
ML = mol

Now, plug in your converted volume and given molarity into the formula.
This leaves you with:
(0.100)(0.025) = mol

Multiply to find your final value for moles.
This results in:
0.0025 mol of HNO3

I hope this is what you’re looking for! :)
