What is Molar mass?
'''Molar mass''' is the mass of a substance that has 6.022 × 10<sup>23</sup> [[atom]]s ([[Avogadro's number]]). The [[mass number]] of an [[chemical element|element]] is equal to the molar mass of the element . The molar mass of a chemical compound is the mass when the compound has 6.022 × 10<sup>23</sup> [[molecule]]s. Molar mass of Chlorine is 35.45 due to consideration of avg molar mass by including mass of its all isotopes. It can be found by adding the molar masses of all of its elements. [[Sodium hydroxide]]'s (NaOH) molar mass can be found by adding the molar mass of sodium, oxygen, and hydrogen, which would be 39.997 g/mo {{chem-stub}} [[Category:Chemistry]] [[Category:Periodic table]]
