For molecular compounds, the molar mass is found by summing the atomic masses of all atoms present in the molecular formula.<\/p>\n\n\n\n<p>In this case, propane is a hydrocarbon with the molecular formula <strong>C\u2083H\u2088<\/strong>, meaning each molecule contains three carbon atoms and eight hydrogen atoms. These numbers reflect how many atoms of each element are bonded together to form one molecule of propane.<\/p>\n\n\n\n<p>To determine the molar mass, we consult the periodic table for atomic masses:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbon atoms each weigh approximately 12.01 g\/mol.<\/li>\n\n\n\n<li>Hydrogen atoms each weigh about 1.008 g\/mol.<\/li>\n<\/ul>\n\n\n\n<p>We multiply the number of each atom in the formula by its atomic mass:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>3 carbons \u00d7 12.01 = 36.03<\/li>\n\n\n\n<li>8 hydrogens \u00d7 1.008 = 8.064<\/li>\n<\/ul>\n\n\n\n<p>Adding these together gives a total molar mass of <strong>44.094 g\/mol<\/strong>, which is rounded to <strong>44.1 g\/mol<\/strong> for simplicity in typical chemical calculations.<\/p>\n\n\n\n<p>Understanding molar mass is crucial for stoichiometry, which involves calculating reactant and product quantities in chemical reactions. For example, if you burn propane as fuel, you need to know its molar mass to calculate how much oxygen is required or how much carbon dioxide is produced.<\/p>\n\n\n\n<p>Hence, the correct molar mass of propane is <strong>44.1 g\/mol<\/strong>, making this the correct answer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the molar mass of propane, C3H8.
