How do i calculate the atomic mass
WebMar 17, 2024 · Well, if you want the molar mass, you add together the mass of every individual element in the compound. Compounds don't have an atomic mass. For example in H_2O Hydrogen (H) has a mass of 1.008 Oxygen (O) has a mass of 16.00 Since there is 2 hydrogen atoms in H_2O we add 1.008 twice or we can say 2(1.008)+16= 18.016 If you … WebJun 2, 2024 · You use the periodic table to look up the mass of each atom (H is 1.01 and O is 16.00). Forming a water molecule gives you a mass of: 1.01 + 1.01 + 16.00 = 18.02 grams per mole of water and you solve with: mass of 1 molecule = …
