WebAug 2, 2024 · Start by converting the mass of each element into moles by looking up the atomic numbers from the periodic table. The atomic masses of the elements are 40.1 g/mol for Ca, 16.0 g/mol for O, and 1.01 g/mol for H. 13.5 g Ca x (1 mol Ca / 40.1 g Ca) = 0.337 mol Ca 10.8 g O x (1 mol O / 16.0 g O) = 0.675 mol O thiago silva injury news
