Its <strong>molecular formula is C\u2086H\u2088O\u2086<\/strong>, which means each molecule consists of 6 carbon atoms, 8 hydrogen atoms, and 6 oxygen atoms.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation (Approx. 300 Words):<\/h3>\n\n\n\n<p>To determine the <strong>molecular formula<\/strong> of a compound, we must know both its <strong>empirical formula<\/strong> and its <strong>molar mass<\/strong>. The empirical formula represents the simplest whole-number ratio of atoms in a compound, while the molecular formula shows the actual number of each type of atom in a molecule.<\/p>\n\n\n\n<p>In the case of ascorbic acid, chemists have analyzed the substance through various methods, such as <strong>elemental analysis and mass spectrometry<\/strong>, and found that it is composed of <strong>carbon (C), hydrogen (H), and oxygen (O)<\/strong>.<\/p>\n\n\n\n<p>From combustion analysis and experimental data, the <strong>empirical formula<\/strong> of ascorbic acid is determined to be <strong>C\u2083H\u2084O\u2083<\/strong>. This empirical unit has a molar mass of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>C (12.01 g\/mol) \u00d7 3 = 36.03 g\/mol<\/li>\n\n\n\n<li>H (1.008 g\/mol) \u00d7 4 = 4.032 g\/mol<\/li>\n\n\n\n<li>O (16.00 g\/mol) \u00d7 3 = 48.00 g\/mol<\/li>\n\n\n\n<li><strong>Total = 88.06 g\/mol<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Now, to find the molecular formula, we compare the <strong>actual molar mass<\/strong> to the <strong>empirical molar mass<\/strong>: Molar&nbsp;mass&nbsp;of&nbsp;ascorbic&nbsp;acid\u00f7Empirical&nbsp;formula&nbsp;mass=176.14\u00f788.06\u22482\\text{Molar mass of ascorbic acid} \u00f7 \\text{Empirical formula mass} = 176.14 \u00f7 88.06 \u2248 2<\/p>\n\n\n\n<p>This means the <strong>molecular formula<\/strong> contains <strong>two empirical units<\/strong>, so we multiply each subscript in the empirical formula by 2: (C3H4O3)\u00d72=C6H8O6(C\u2083H\u2084O\u2083) \u00d7 2 = C\u2086H\u2088O\u2086<\/p>\n\n\n\n<p>Thus, the molecular formula is <strong>C\u2086H\u2088O\u2086<\/strong>.<\/p>\n\n\n\n<p>This formula not only matches the compound\u2019s molar mass but also aligns with its known structure and biological function. Ascorbic acid is a crucial antioxidant and plays a key role in collagen synthesis and immune function. Its specific arrangement of atoms allows it to donate electrons and neutralize free radicals in the body.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/04\/image-157.png\" alt=\"\" class=\"wp-image-207106\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Ascorbic acid has a molar mass of 176.14 g\/mol.
