Web11 nov. 2024 · the weight of CO₂ (w) is 22 gm. The number of molecules removed (n) = 3 × 10²² molecules. To find, The amount of weight and moles of CO₂ left. Calculation, The number of moles of 22 gm of CO₂ is . n = 22/44. ⇒ n = 0.5. We know that 1 mole of CO₂ contains 6.023 × 10²³ molecules. So 0.5 moles contain 3.061 × 10²³ molecules. WebJust as a dozen implies 12 things, a mole (mol) represents 6.022 × 10 23 things. The number 6.022 × 10 23, called Avogadro’s number after the 19th-century chemist Amedeo Avogadro, is the number we use in chemistry to represent macroscopic amounts of atoms and molecules.
