Nomenclature of Some Special Cations. I. Cations that do not require Roman numerals: Previously you had learned that elements in Groups IA and IIA, and aluminum form cations of a. fixed charge. You are now going to add on to this list, a few more ions in the transition metals that. also do not require a fixed charge because they generally form only ions with charges as shown. below:
Take an example, if a recipe calls for 350 grams of plain flour, then you refer to a conversion table saying it's about 2.5 cups.
the USDA says 1 cup of wheat flour, white (either enriched or unenriched) is 137g or 4.83 oz. King Arthur, on the other hand, maintains that a cup of bread or AP flour is 4.25 oz (120g), Peter Reinhart says it's 4.5 (127g) Rose Levy Beranbaum says it's 5.5 (157g). Jeffrey Hamelman (who works for KA) says 4.8 (136g) which obviously conflicts with the KA amount.
