A 25 mL sample of 0.100 M HNO3 completely reacts with NaOH according to this equation:

HNO3(aq) + NaOH (aq) ⟶ NaNO3(aq) + H2O(l)

How many moles of HNO3 are in the sample?
mol HNO3

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

0.0025 mol of HNO3 is in the sample.

What are moles?

A mole is defined as 6.02214076 × [tex]10^{23}[/tex]of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
