Mole
,→Calculating Moles from Masses
==Key Stage 4==
===Meaning===
A [[mole]] is an [[SI Unit]] used to show [[Avogadro Constant|6.02x10<sup>23</sup> ]] [[particle]]s of a [[chemical]].
===About Moles===
: [[Mole]]s are based on the number of [[Carbon]] [[atom]]s in exactly 0.012kg (12g) of [[Carbon]].
: [[Mole]]s are used to give a conversion between the number of [[atom]]s in a [[substance]] and useful quantities for [[Chemical Reaction|chemical reaction]]s. It would not be useful to talk about 1,000,000,000 [[atom]]s in a [[Chemical Reaction|chemical reaction]] because that would be such a small amount of the [[chemical]] (0.0000000000000017g).
: The [[Relative Atomic Mass|relative atomic mass]] of an [[element]] is the [[mass]] of 1 [[mole]] or the [[mass]] of [[Avogadro Constant|6.02x10<sup>23</sup> ]] [[atom]]s. So 1g of [[Hydrogen]] is 1 [[mole]] and contains [[Avogadro Constant|6.02x10<sup>23</sup> ]] [[atom]]s. 235g of [[Uranium-235]] is 1 [[mole]] and contains [[Avogadro Constant|6.02x10<sup>23</sup> ]] [[atom]]s.
