WebThe chemical formula Mg (OH)₂ , indicates that in one mole of the compound, there are one mole of Mg atoms, two moles of O atoms, and two moles of H atoms, for a total of five moles of atoms. 1 mole of atoms = 6.022 × 10²³ atoms Use dimensional analysis to calculate the number of atoms in 10 moles of Mg (OH)₂. WebThe mass of one atom is usually expressed in atomic mass units (amu), which is referred to as the atomic mass. An amu is defined as exactly 1/12 of the mass of a carbon-12 atom and is equal to 1.6605 \times 10 −24 g. Protons are relatively heavy particles with a charge of 1+ and a mass of 1.0073 amu.
