Error: We couldn't find a conversion between moles and grams [incompatible types] To complete this calculation, you need to know what substance you are trying to convert. This is a different version than Moles to Grams, Grams to Moles and Moles to Molecules listed in my store but follows the same format. 1) How many moles of carbon tetrafluoride, CF 4, are in 352 grams of CF 4? Convert grams to moles and find the empirical formula. The reason is that the molar mass of the substance affects the conversion. 2) How many grams. E.g. The reactant that is used up is the limiting reagent. In real-life chemical reactions, not all of the reactants present convert into product. 4) If this problem were set up like the proportion above, you would have this: The SI base unit for amount of substance is the mole. 238 x 75 = 17,850 grams 9) How many grams are in 4.5 moles of sodium fluoride, NaF? 1.95 mole Co 7.
