What is the empirical formula mass of a compound? How do you find the empirical formula from the molecular formula? What is the formula for dinitrogen monoxide? What is the empirical formula of C4H8? What is the formula for an ionic compound made of carbon and oxygen? What is the condensed...
RDBE values can be calculated the following formula [31]: RDBE = C+Si - 1/2(H+F+Cl+Br+I) + 1/2(N+P)+1 (1) Each element symbol here represents the count of atoms of this element in the molecular formula. The elements oxygen and sulphur were not taken into account. This ...
There are several different types of sugar, but, generally, when you ask for the molecular formula of sugar, you are referring to table sugar or sucrose. The molecular formula for sucrose is C12H22O11. Each sugar molecule contains 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. Read...
