What is a Formula Unit of a Compound
Copper sulphate can be written as CuSO4. But since salts are a repeating solid lattice of ions there is no molecule and therefore no molecular formula for salts. Formula Unit Easy Science Easy Science Science Rules Ap Chemistry Calculate the edge length of a. . NaCl is the formula unit for sodium chloride which is made up of one Na ion. A formula unit is simply writing the susbtance in chemical names with valencies. The formula of unit Mass can be calculated for those compounds which do not have any discrete molecules but have ions as their constituents unit. The only difference is that we use the word formula unit for those substances whose constituent particles are ions. A formula unit is the simplest formula of an ionic compound and therefore you can think of it as the empirical formula. It is only applicable to compounds that do not form molecules such as ionic compounds and. Definition of formula unit
