Formula Mass Vs Molecular Mass. For simple molecules, formula mass and molecular mass are the same. Since atoms, molecules and unit cells are extremely small particles;
… and to determine the molecular mass of ethanol, the other formula given in the question, we follow the same steps. It is measured in daltons (da or u). For example, molecular mass of chlorine (cl2) is 71 amu, of water (h2o) is 18 amu and that of carbon dioxide.
In chemical formula you may use:
7 molar mass 7 1 mol of 12 c = g of c = x atoms of c g of 12 c is its molar mass taking into account all of. The molecular mass the sum of the average masses of the atoms in one molecule of a substance, each multiplied by its subscript. What is the difference between molecular mass and formula mass ? For example, molecular mass of chlorine (cl2) is 71 amu, of water (h2o) is 18 amu and that of carbon dioxide.
