The '''Avagadro Avogadro Constant''' is the number of [[atom]]s in 12g of [[Carbon]]. '''6.02x10²³ ''' [[atom]]s per mol[[mole]].

===About the Avagadro Avogadro Constant===: The '''Avagadro Avogadro Constant''' is used to state the number of [[atom]]s or [[molecule]]s in a [[mole]] of a [[substance]].: The '''Avogadro Constant''' is normally written in standard form as '''6.02x10²³''' = '''602,000,000,000,000,000,000,000''' correct to 3 [[Significant Figures]].: 1 [[mole]] of an [[element]] contains '''6.02x10²³ ''' [[atom]]s of that [[element]].: 1 [[mole]] of a [[molecule]] contains '''6.02x10²³ ''' [[molecule]]s. ===Extra Information==={{#ev:youtube|https://www.youtube.com/watch?v=TEl4jeETVmg}} ===References=======AQA====:[https://www.amazon.co.uk/gp/product/178294639X/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=178294639X&linkCode=as2&tag=nrjc-21&linkId=51599bb45a2bfaf7c1b6a978b2ca2616 ''Avogadro constant, page 106, GCSE Combined Science Trilogy; Chemistry, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1782945962/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945962&linkCode=as2&tag=nrjc-21&linkId=476bb5c8d1dfb5c08ac81b6d4d1c98d8 ''Avogadro constant, page 112, GCSE Chemistry, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1782945571/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945571&linkCode=as2&tag=nrjc-21&linkId=9e29fad914244909903e5e93f8a01d51 ''Avogadro constant, page 42, GCSE Chemistry; The Revision Guide, CGP, AQA '']:[https://www.amazon.co.uk/gp/product/1471851346/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1471851346&linkCode=as2&tag=nrjc-21&linkId=3ac654f4b0da781c49c855a1af4c92ea ''Avogadro constant, page 65, GCSE Chemistry, Hodder, AQA '']:[https://www.amazon.co.uk/gp/product/1471851354/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1471851354&linkCode=as2&tag=nrjc-21&linkId=9012a0d354024419214fb3ad5ac44ba0 ''Avogadro constant, pages 178-9, GCSE Combined Science Trilogy 1, Hodder, AQA '']:[https://www.amazon.co.uk/gp/product/0198359381/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359381&linkCode=as2&tag=nrjc-21&linkId=47c8d1ae58d8b3a5e2094cd447154558 ''Avogadro constant, pages 62-63, GCSE Chemistry; Third Edition, Oxford University Press, AQA '']====Edexcel====:[https://www.amazon.co.uk/gp/product/1292120193/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1292120193&linkCode=as2&tag=nrjc-21&linkId=572df39392fb4200db8391d98ae6314e ''Avogadro constant, page 220, GCSE Combined Science, Pearson Edexcel '']:[https://www.amazon.co.uk/gp/product/1292120215/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1292120215&linkCode=as2&tag=nrjc-21&linkId=8f96ddb76196848bafdb124354e4cf77 ''Avogadro constant, page 76, GCSE Chemistry, Pearson, Edexcel '']:[https://www.amazon.co.uk/gp/product/1782945725/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945725&linkCode=as2&tag=nrjc-21&linkId=694be7494de75af3349537d34e13f7f0 ''Avogadro’s constant, page 28, GCSE Chemistry; The Revision Guide, CGP, Edexcel '']:[https://www.amazon.co.uk/gp/product/1782945741/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945741&linkCode=as2&tag=nrjc-21&linkId=30da4f2178da182547b62a7329d13b57 ''Avogadro’s constant, page 91, GCSE Combined Science; The Revision Guide, CGP, Edexcel '']:[https://www.amazon.co.uk/gp/product/1782948147/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782948147&linkCode=as2&tag=nrjc-21&linkId=f63dcd8345f4e49c717b39a228a36c7c ''Avogadro’s constant, pages 85, 86, GCSE Chemistry, CGP, Edexcel ''] ====OCR==== :[https://www.amazon.co.uk/gp/product/0198359829/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=0198359829&linkCode=as2&tag=nrjc-21&linkId=90e8d7b4f039d53035238fa0320fe00b ''Avogadro constant, page 97, Gateway GCSE Chemistry, Oxford, OCR '']:[https://www.amazon.co.uk/gp/product/1782945679/ref=as_li_tl?ie=UTF8&camp=1634&creative=6738&creativeASIN=1782945679&linkCode=as2&tag=nrjc-21&linkId=a2db42f7b4bdf10cafaafa3bb9120940 ''Avogadro’s constant, page 38, GCSE Chemistry; The Revision Guide, CGP, OCR Gateway ''] ==Key Stage 5=====Meaning===The [[Avogadro Constant]] is the number of atoms in 12 grams of carbon-12, approximately '''6.02x10²³''' atoms per [[mole]]. ===About the Avogadro Constant=== *The [[Avogadro Constant|Avogadro constant]] is a fundamental constant in chemistry and physics.*The [[Avogadro Constant|Avogadro constant]] is used to calculate the number of [[particle]]s in a given amount of substance.*One [[mole]] of any substance contains [[Avogadro Constant|Avogadro]]'s number of particles.*The value of the [[Avogadro Constant|Avogadro constant]] is '''6.02x10²³''' mol^-1.*It is used in determining the [[Molar Mass|molar mass]] of substances.*The [[Avogadro Constant|Avogadro constant]] is essential for converting between [[atom]]ic scale and macroscopic scale measurements.*The [[Avogadro Constant|Avogadro constant]] is named after the Italian scientist [[Amedeo Avogadro]], who first proposed the concept.
