An numerong 6.02214076×10<sup>23</sup> (an numerong Avogadro) iyo an napili ngarig an masa nin sarong mole kan sarong kompuwestong kimikal sa gramo iyo numerikal na magkaparehas, para sa kadaklan nin mga praktikal na obheto, pasiring sa media na masa kan sarong molekula nin kompuwesto sa daltons. Halimbawa, an sarong mole nin tubig igwa nin 6.02214076×10<sup>23</sup> na molekula, kun sain an saiyang kabilugang gabat iyo harus 18.015 na gramo asin an media na gabat nin sarong molekula iyo harus 18.015&nbsp;na daltons.
An mole iyo mahiwas na ginagamit sa kimika bilang sarong pasil na paagi para mabilang an mga reaktante asin produkto nin reaksyong kimikal. Halimbawa, an ekwaksyong kimikal na {{nowrap|2H<sub>2</sub> + O<sub>2</sub> → 2H<sub>2</sub>O}} pwede sabihon na sa kada 2&nbsp;mol nin dihydrogen (H<sub>2</sub>) asin 1&nbsp;mol nin dioxygen (O<sub>2</sub>) na nagreakto, 2&nbsp;mol nin tubig (H<sub>2</sub>O) an mapoporma. An mole pwede man magamit para masukol an bilang nin mga atomo, iyono, elektron, o iba pang mga entidad. An konsentrasyon nin sarong solusyon iyo harus nasasambit gamit an [[molaridad]] (''molarity''), na may boot-sabihon na an bilang nin natunaw na substansya sa mole kada yunit nin bolyum kan solusyon, kun sain an yunit tipikal na ginagamit iyo an "molesmole kada litro" (mol/l), pinapalipot man na ''M''.
 
An terminong '''gramo-molekula''' (g mol) iyo nagligad na piggagamit para sa "''mole of molecules''",<ref>International Bureau of Weights and Measures (2006), ''The [http://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf International System of Units (SI)]'' (PDF) (8th ed.), pp. 114–15, ISBN <bdi>92-822-2213-6</bdi>, [https://web.archive.org/web/20170814094625/http://www.bipm.org/utils/common/pdf/si_brochure_8_en.pdf archived] (PDF) from the original on 2017-08-14</ref> sagkod an '''gramo-atomo''' (g atom) para sa "''mole of atoms''". Halimbawa, an 1 mole nin MgBr<sub>2</sub> iyo 1&nbsp;gramo-molekula nin MgBr<sub>2</sub> pero 3&nbsp;gramo-atomo nin MgBr<sub>2</sub>.<ref>{{cite journal|doi=10.1088/0953-8984/15/6/315|last8=Hinderer|bibcode=2003JPCM...15..883W|arxiv=cond-mat/0208169|pages=883–893|issue=6|volume=15|year=2003|journal=Journal of Physics: Condensed Matter|title=Specific heat of MgB<sub>2</sub> after irradiation|display-authors=etal|first9=Alain|last9=Junod|first8=Joerg|first7=Harald W.|last1=Wang|last7=Weber|first6=Michael|last6=Eisterer|first5=Bernard|last5=Revaz|first4=Pierre12|last4=Toulemonde|first3=Ilya|last3=Sheikin|first2=Frédéric|last2=Bouquet|first1=Yuxing|s2cid=16981008}}</ref><ref>{{cite journal|doi=10.1103/PhysRevB.72.024547|last7=Junod|bibcode=2005PhRvB..72b4547L|arxiv=cond-mat/0502193|pages=024547|issue=2|volume=72|year=2005|journal=Phys.
