How many atoms of hydrogen are in 10 g of water? - Quora
Web26 mrt. 2024 · One can calculate the number of moles in a substance using the above formula. The number of moles in 36 g of water is calculated as, n = 36 g 18 g / m o l = 2 m o l e s. Hence, the number of moles in 36 g of water is two moles. Additional information: The quantity of chemical substance in a reaction is given mole fraction. WebSolution: Using the generic expression to convert g to atoms: Number of Atoms = (Given Mass/Molar Mass) * Avogadro’s Number. Number of Atoms = (78/40.078) * 6.02 * 10^ {23} Number of Atoms = 1.9462 * 6.02 * 10^ {23} Number of Atoms = 1.171 * 10^ {+24} For further verification, you can let this grams to atoms calculator do that for you in seconds. reading specialist degree online programs
