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.
How many cups are in 250 grams of flour? 250 grams = approx. How many cups is 100 grams of milkcream and How many cups is 250 grams of sugar?   Answer   I guess that depends on whether you are using heavy or light cream, and at what temperature. At 4.4 Deg C, Heavy cream is 1.008 kg/L, or 238.5 g/cup (Convâ¦ersion factors used: 4.2268 cup/L, 1000 g/kg).
