Applications of the Mole.
| Known Information | Multiply By | Result |
|---|---|---|
| Mass of substance (g) | 1/Molar mass (mol/g) × Avogadro’s constant (atoms/mol)) | Atoms (or molecules) |
How do you calculate N in chemistry?
n = m/M n is the amount of substance, in moles, mol. m is the mass of the substance, in grams, g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1.
How do you find N atoms?
To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro’s number: 6.02 x 10^23.
How do you find N in electrochemical cell?
General rule: Find the number of electrons in each balanced HALF-reaction. If they match, that is n (First example). If they don’t match, take the lowest common multiple, and that is n (Second/third examples).
How do you convert moles to atoms?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
How do you convert moles to particles?
From moles to particles (atoms, molecules, or formula units): Multiply your mole value by Avogadro’s number, 6.02 × 1023.
