Witrynato convert from g/dm3 to mol/dm3, divide by the relative formula mass Remember: the molar mass is the Ar or Mr in grams per mol. Example Calculate the concentration of … WitrynaIts formula mass is 58.44 amu. Note that the average masses of neutral sodium and chlorine atoms were used in this computation, rather than the masses for sodium cations and chlorine anions. This approach is perfectly acceptable when computing the formula mass of an ionic compound.
