Molecules, Moles and Avogadro
WebThe molecular mass of carbon dioxide is 44.01amu. The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g. The molar masses are 44.01g/mol and 78.04g/mol respectively. Web14 jan. 2024 · • The molecular weight of CO2 is 44 gram per mole. • So, the number of moles will be, Number of moles = 54 g/44 g/mol = 1.227 moles Now to determine the molecules, there is a need to multiply the moles with the Avogadro's constant, that is, 6.022 × 10²³. This comes out to be as, = 1.227 moles × 6.022 × 10²³ = 7.39 × 10²³ … florida atlantic u football helmets
