And this is the molecular must from the last of his company. The molecular structure of chloroform. This approach is perfectly acceptable when computing the formula mass of an ionic compound. To Follow Or Unfollow? Determine the formula mass/ element 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. The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. What is the empirical formula for a compound that contains 83.01% K and 16.98% O by mass?
