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. WebThis formula can be written as: Number of Atoms or Molecules = (Number of Moles)* (6.022*1023) The relationship between the atomic mass unit (amu) and the gram is given by: 1 amu = (1gram)/ (6.022*1023) = … WebMay 20, 2024 · 3.59molFe2O3 × ( 3molSO3 1molFe2O3) = 10.77molSO3. The mol Fe 2O 3 units cancel, leaving mol SO 3 unit. Now, we take this answer and convert it to grams of SO 3, using the molar mass of SO 3 as the conversion factor: 10.77molSO3 × (80.06gSO3 1molSO3) = 862 gSO3. Our final answer is expressed to three significant figures. r c woods car sales hounslow
