Avogadro's number: Avogadro's number is a very large number, equal to 6.0221409×1023. Mole: A mole is Avogadro's number of atoms or molecules or particles. Mole Ratio General Chemical Formula: AaBbCc... where the capital letters represent the atomic elements and the small letters represen...
The formula of a well-known compound, water, is H2O. Water is made up of molecules, and the formula shows that each molecule consists of two atoms of hydrogen, H, bonded to an atom of oxygen, O. The subscript 2 indicates that there are two atoms of hydrogen in the molecule; where ...
The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure ofthe numberof atoms or molecules in a bulk sample of matter. Amoleis defined asthe amount of substance containing the same number of discrete entities (atoms, molecules, ions,...

The molecular formula of ribose is C5H10O5, which can be reduced to the empirical formula CH2O. How to Determine Empirical Formula Begin with the number of grams of each element, which you usually find in an experiment or have given in a problem. ...
(formula weight) of glucose is 30 (either no units or else grams per mole), while the molecular mass (molecular weight) is 180.156 g/mol. Whenever you see a molecular formula where you can divide the subscripts by a whole number (usually 2 or 3), you know to expect the formula mass...
