Avogadro's Number Is Useful For

Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 10 23. The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any).See alsoAvogadro’s law. 5.11x10 23 atoms of lithium is equal to how many moles? (to find moles, you must divide atoms by Avogadro's number).

ävōgä´drō [for Amedeo Avogadro], number of particles contained in one mole of any substance; it is equal to 602,252,000,000,000,000,000,000, or in scientific notation, 6.02252×10²³. For example, 12.011 grams of carbon (one mole of carbon) contains 6.02252×10²³ carbon atoms, and 180.16 grams of glucose, C₆H

Avogadro's Number Is Equal To One

₁₂O₆, contains 6.02252×10²³ molecules of glucose. Avogadro's number is determined by calculating the spacing of the atoms in a crystalline solid through X-ray methods and combining this data with the measured volume of one mole of the solid to obtain the number of molecules per molar volume.
