Potassium
Salt ratio not recorded. The source lists this compound as the parent acid and the metal without saying how many of each, so the formula and molar mass are for one of each. Check the formula on the supplier's label before you weigh it.
The catalogue keeps a structure only when a source confirms both the CAS number and a name, so it keeps none rather than the wrong compound. Draw it in Covalent
