It is expressed in units of grams per mole (&nbsp;g\/mol&nbsp;). To find the molar mass of methane (CH\u2084), one must sum the atomic masses of its constituent atoms based on its chemical formula.<\/p>\n\n\n\n<p>The calculation proceeds in a straightforward manner. First, identify the elements present in the molecule and the number of atoms of each element. The formula CH\u2084 indicates that a single molecule of methane contains one carbon (C) atom and four hydrogen (H) atoms.<\/p>\n\n\n\n<p>Next, find the standard atomic mass of each element from the periodic table. The atomic mass of carbon is approximately 12.011&nbsp;g\/mol&nbsp;, and the atomic mass of hydrogen is approximately 1.008&nbsp;g\/mol&nbsp;.<\/p>\n\n\n\n<p>Then, calculate the total mass contribution from each element in the compound.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>For carbon, its contribution is the mass of one atom: 1 atom \u00d7 12.011\u00a0g\/mol\u00a0= 12.011\u00a0g\/mol\u00a0.<\/li>\n\n\n\n<li>For hydrogen, its contribution is the mass of four atoms: 4 atoms \u00d7 1.008\u00a0g\/mol\u00a0= 4.032\u00a0g\/mol\u00a0.<\/li>\n<\/ul>\n\n\n\n<p>Finally, add the mass contributions from all the elements together to get the molar mass of the methane molecule.<br>Molar Mass of CH\u2084 = (Mass of Carbon) + (Mass of Hydrogen)<br>Molar Mass of CH\u2084 = 12.011&nbsp;g\/mol&nbsp;+ 4.032&nbsp;g\/mol&nbsp;= 16.043&nbsp;g\/mol&nbsp;.<\/p>\n\n\n\n<p>For most general chemistry purposes, this value is rounded to two decimal places, resulting in 16.04&nbsp;g\/mol&nbsp;. This number is fundamental in stoichiometry, as it provides a direct conversion factor between the mass of a methane sample and the number of moles it contains, which is crucial for predicting reactant and product quantities in chemical reactions.thumb_upthumb_down<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-599.jpeg\" alt=\"\" class=\"wp-image-235374\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the molar mass of methane ()? 18 g\/mol 20. g\/mol 12 g\/mol The Correct Answer and Explanation is: The correct answer is&nbsp;16.04&nbsp;g\/mol&nbsp;.
