The gram molecular mass of HF is 20.01. Therefore, 0.589 mole has a mass of 11.79 grams and is sufficient to form 0.589 mole of sodium fluoride* when sodium is present in excess. The gram molecular mass of sodium fluoride is 41.99, so that 0.589 grams of it has a mass of 24.7 grams, to the justified number of significant digits. __________________________ The formula unit of both hydrogen and sodium fluorides contains a single fluorine atom.
AlNO33, KI, HF, CH3OH
2,297 kg HF are needed.
HF This is an example of a covalent compound, so prefixes are needed to determine how many of each atom are in the compound. Since there are none, it is given that there are one of each.
