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. Web10 jul. 2024 · Hydrogen atoms account for around 90% of the total atoms in the universe, according to Los Alamos National Laboratory, and an even higher percentage of the atoms in stars, which we are focusing on. Web3 apr. 2024 · You can see that in Ammonium hydroxide (NH4OH), there is 1 Nitrogen atom, 5 Hydrogen atoms and 1 Oxygen atom. So, Molar mass of Ammonium hydroxide (NH4OH) = Molar mass of 1 Nitrogen (N) atom + Molar mass of 5 Hydrogen (H) atoms + Molar mass of 1 Oxygen (O) atom. = 14.007 + (1.008) 5 + 15.999 = 14.007 + 5.04 + 15.999 = 35.046 … text after first date examples
