- 12. To convert between mass and number of moles. The conversion factor between mass and number of moles is called molar mass. By consulting the periodic table , we can determine that the molar mass of NaClNaCl is 23.0 g/mole+35.5 g/mole=58.5 g/mole23.0 g/mole+35.5 g/mole=58.5 g/mole This number tells us that 1 molemole of NaClNaCl has a mass of 58.5 gg .
