To find the number of carbon atoms, calculate the moles of CO from the given mass and use Avogadro\u2019s number to convert to atoms. Similarly, to find the mass of oxygen in a specific number of CO molecules, convert molecules to moles, recognize that there is one oxygen atom per molecule, and then calculate the mass using the molar mass of oxygen.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1241.jpeg\" alt=\"\" class=\"wp-image-40224\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1241.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1241-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1241-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many atoms of carbon are present in 6.81 grams of carbon monoxide, CO?
