Calculate the mass of 12.044 oxygen atoms
WebMar 16, 2024 · Total number of atoms = 0.0092 x 6.022 x 10 23 = 0.054 x 10 23 atoms. Molecular mass of Water (H 2 O) is 18g/mol. There are 3 atoms in the molecule. So, 1g of water means 1/18 moles = 0.055 moles. Total number of atoms = 3 x 0.055 x 6.022 x 10 23 = 1.003 x 10 23 atoms. Thus 1g of butane has greatest number of atoms.
