WebThe weight in atomic mass units of each of the atoms in a given formula is the molecular weight of a substance. An atomic mass unit is described as 1/12 th the weight of the carbon-12 isotope. The old symbol was amu, while the most correct symbol is … WebSolution: Since sodium carbonate contains two atoms of sodium, one atom of carbon and three atoms of oxygen. The molecular weight would be. Na : 2 x 23.0 = 46. C : 1 x 12.0 = 12. O : 3 x 16 = 48. When we add up the total values i.e, 46 + 12 + 48 = 106. Therefore, the molar mass of Na 2 CO 3 is 106 g/mol.
