Avogadro&#8217;s number, which is approximately 6.022 x 10\u00b2\u00b3 particles per mole, provides the conversion factor between the number of individual particles (like molecules) and the amount in moles. The molar mass, given as 180.16 grams per mole (&nbsp;g\/mol&nbsp;) for glucose, tells us the mass of one mole of that substance.<\/p>\n\n\n\n<p>The calculation involves a two-step process. First, we convert the given number of glucose molecules into moles. This is done by dividing the number of molecules by Avogadro&#8217;s number:<\/p>\n\n\n\n<p>Moles = 256 molecules \/ (6.022 x 10\u00b2\u00b3 molecules\/mol) \u2248 4.25 x 10\u207b\u00b2\u00b2 moles<\/p>\n\n\n\n<p>This result shows that 256 molecules is an exceptionally small fraction of a mole, which is expected since a mole contains an enormous number of molecules.<\/p>\n\n\n\n<p>Second, we convert this amount in moles into mass using the molar mass of glucose. We multiply the number of moles by the molar mass:<\/p>\n\n\n\n<p>Mass = (4.25 x 10\u207b\u00b2\u00b2 moles) \u00d7 (180.16&nbsp;g\/mol&nbsp;) \u2248 7.66 x 10\u207b\u00b2\u2070 grams<\/p>\n\n\n\n<p>This calculated mass is an extremely small number, far smaller than any of the numerical options provided. The option &#8220;180.16 g&#8221; represents the mass of one full mole of glucose, not 256 molecules. The option &#8220;46120 g&#8221; is the incorrect result of multiplying the number of molecules directly by the molar mass (256 \u00d7 180.16), confusing molecules with moles. Since our calculated mass of approximately 7.66 x 10\u207b\u00b2\u2070 grams does not match any of the other choices, the correct selection is &#8220;None of the other choices&#8221;.<\/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-banner6-294.jpeg\" alt=\"\" class=\"wp-image-252910\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the mass of 256 molecules of glucose, C6 H12 O6 The Correct Answer and Explanation is: The correct answer is&nbsp;None of the other choices.
