Gram atomic mass of magnesium
WebSep 24, 2024 · As measured by mass spectrometer the mass of one atom of C-12 atom is found to be 1.992648 × 10 -23 g. Since 1 mole of C-12 atoms is 12g. Therefore, the number of atoms present in 1 mole = 12g / 1.992648*10 -23 g atom -1 or 6.0221367 × 10 23 atoms. The value of 1 mole is known as Avogadro’s Constant.
