Hexavalent chromium (chromium(VI), Cr(VI), chromium 6) is the chromium in any chemical compound that contains the element in the +6 oxidation state (thus hexavalent).Virtually all chromium ore is processed via hexavalent chromium, specifically the salt sodium dichromate.Approximately 136,000 tonnes (300,000,000 lb) of hexavalent chromium were produced in 1985. Give the formula for iron (III) oxide. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. Lead chromate adopts the monazite structure, meaning that the connectivity of the atoms is very similar to other compounds of the type MM'O4. molar mass and molecular weight.
