Class 11 Chemistry : Determining Empirical and Molecular Formula of Compounds

Class 11 Chemistry : Determining Empirical and Molecular Formula of Compounds Chemistry notes for class 11 : We offer Biology, Chemistry, and Physics notes, CBSE guide, last year question papers for board exams preparation. Our sole objective is to provide quality and result oriented education as well as guidance to the youth of the country in order to achieve their goals.  Molecular formula It describes the  exact number and type of atoms  in a single molecule of a compound. The constituent elements are represented by their chemical symbols, and the number of atoms of each element present in each molecule is shown as a subscript following that element’s symbol. Empirical formula The  empirical formula  of a compound is defined as the formula that shows the ratio of elements present in the compound, but not the actual numbers of atoms found in the molecule. The ratios are denoted by subscripts next to the element symbols. The empirical formula is also known as the  si
