In this case, O\u2082 consists of two oxygen atoms, and since each oxygen atom has a molar mass of 16.00 g\/mol, the molar mass of the O\u2082 molecule is double that. The reason we use the molar mass in grams per mole (g\/mol) is that it gives us the mass of one mole of molecules. One mole of any substance contains Avogadro\u2019s number of particles, which is approximately 6.022\u00d710236.022 \\times 10^{23}6.022\u00d71023 particles.<\/p>\n\n\n\n<p>So, when you have one mole of O\u2082 (32 grams), you are holding 6.022\u00d710236.022 \\times 10^{23}6.022\u00d71023 O\u2082 molecules, and this helps when converting between mass, moles, and molecules in stoichiometric calculations.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1813.jpeg\" alt=\"\" class=\"wp-image-268784\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the molar mass of O2? show your math below.
