What is the normality formula?

Answer 1

The formula for normality is number of equalants over liters of solution. Example if the questions gives you 86g of H2SO4 WITH A VOLUME OF 22 L and what is its NORMALITY? This is how You start the question. First H2SO4 is a acid not a base it contains H+ ions.

So 1 mol of H2SO4 - 2 mols of H+

your probaly wondering why this 2 mols of H+ because next to the H theres a 2

you never want 2 mols H+ you have to get one

so you u cut it in half (note it can never have more than one mole so you have to half it or if its 3 you have to make it to 1 third or 4 1 forth)

Next you go half mol of H2SO4 - 1 mole of H+

Then after you go One EQUALANT - 1 half mol of H2SO4

Then EQUALANT WEIGHT - HALF the molar mass (but note its not always half just because you have two moles. this goes for the same at the top if the moles are 3 then you multiply the molar mass by 1 third)

after the 4 steps you make the equalant weight equal to the molar mass

then after u get a mass

then you put the mass from the question you divide it with the mass u just got from the top

you get a anwer after you get the answer in EQUALANT

THEN AFTER U GOT YOUR EQUALANT YOU PLUG IN INTO THE FORMULA NORMALITY = EQ OVER LITERS

Answer 2

Formula for Normality : number of equivalents/liter of the solution If you have questions that involve finding the normality, then you have to give me some information on what you are trying to look for.

Answer 3

The normality (N) of a solution is calculated as the number of equivalents of the solute divided by the volume of solution (in liters). The formula is given as: Normality (N) = Number of equivalents / Volume of solution (in liters).

Answer 4

Normality is the number of equivalents (how many H+ ions) times molarity of the substance. The molarity of a substance is the number of moles of a solute per liters of solution.
