WebThe formula mass of this molecular unit is calculated by adding together the atomic masses of three calcium atoms, two phosphorus atoms, and eight oxygen atoms. B Taking atomic masses from the periodic table, we obtain C Adding together the masses gives the formula mass of Ca 3 (PO 4) 2: 120.234 amu + 61.947522 amu + 127.9952 amu = 310.177 amu WebSolution: Since sodium carbonate contains one carbon atom, two sodium atoms, and three oxygen atoms, the molecular weight is. Na : 23.0 x 2 = 46. C : 12.0 x 1 = 12. O : 16 x 3= 48. If molecular formula calculator add up the total value, which is 12 + 46 + 48 = 106. Therefore, the molar mass of Na2CO3 is 106 g/mol.
