What is a molecular formula? Could someone give examples? Not a website
Thanks
A molecular formula is a representation of a molecule that shows the types and numbers of atoms present in a molecule. It gives you the actual number of atoms of each element in a compound. For example, the molecular formula for water is H2O, which means that one molecule of water contains two atoms of hydrogen (H) and one atom of oxygen (O). Another example is the molecular formula for methane, which is CH4. This represents one carbon (C) atom and four hydrogen (H) atoms in each molecule of methane.
To find molecular formulas, you can use various sources like textbooks, scientific literature, or chemical databases. These sources provide the necessary information about the composition of molecules. By studying the chemical structure and analyzing experimental data, scientists can determine the molecular formula for a specific compound.
