A25 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

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
