    AVOGADRO'S NUMBER A principle stated in 1811 by the Italian chemist Amadeo Avogadro (1776-1856) that equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties. This number (Avogadro's number) is 6.023 X 10 23. It is the number of molecules of any gas present in a volume of 22.41 L and is the same for the lightest gas (hydrogen) as for a heavy gas such as carbon dioxide or bromine. Avogadro’s Hypothesis. In 1811, Amedeo Avogadro (1776–1856) (born Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto) looked at Gay-Lussac’s results and concluded that when they are at the same temperature and pressure, equal volumes of gas (like two balloons of the same size) contain the same number of “particles.” Avogadro's number: 1 n the number of molecules in a mole of a substance (approximately 602,250,000,000,000,000,000,000) Synonyms: Avogadro number Type of: constant a number representing a quantity assumed to have a fixed value in a specified mathematical context The number of phosphorous (P) atoms is equal to Avogadro's Number: {eq}6.022 \times 10^{23} {/eq} Since we have exactly Avogadro's Number of phosphorous atoms, we can say that we have exactly 1 ... The NIST 2007 value of Avogadro's number is 6.022 141 79 ± 0.000 000 30 X 1023 mol–1. For most calculations, a rounded value of 6.022 X 1023 (four significant figures) is satisfactory. This is an incredibly large number. A mole of say, grapefruit, stacked together, would occupy the volume of the entire planet earth! Avogadro was an Italian Physicist who first described the Avogadro constant as a hypothesis in 1811. He was trying to understand why in chemical reactions involving gases the observation that equal volumes of different gases had the same number of moles.

    Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules". For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant. his law explains how, under the same condition of temperature and pressure, equal volumes of all gases contain the same number of molecules. Avogadro's number (N A) is N A = 6.022×10 23 : 1 mol of any gas at 273 K (0_C) and 1 atm has a volume of 22.4 L. The conditions 273 K and 1 atm are the standard ...

    1) Avogadro's Number compared to the Population of the Earth: We will take the population of the earth to be six billion (6 x 10 9 people). We compare to Avogadro's Number like this: 6.022 x 10 23 divided by 6 x 10 9 = approx. 1 x 10 14. In other words, it would take about 100 trillion Earth populations to sum up to Avogadro's number.
