The number and type of element contained within a substance- molecular or ionic.
For example
C2H5OH
C = Carbon
H = Hydrogen
O = Oxygen
This shows there's 2 Carbon atoms, 6 Hydrogen atoms, and 1 Oxygen atom. This way of representing this molecule shows people that there's an OH functional group at the end of the molecule.
It can also be expressed as;
C2H6O

If you break down the chemical by it's elements and apply some simple rules, you can find the formula for a chemical compound.
The first step to determine the formula of a new substance is to determine the elements present in the substance through experimentation or analysis. Once the elements are identified, the next step is to determine the ratio of atoms of each element in the substance to establish the chemical formula.
To determine the total number of elements in a chemical formula, you count the atoms of each element present in the formula. Each element is represented by its chemical symbol (e.g., H for hydrogen, O for oxygen). The sum of the atoms of each element gives you the total number of elements in the chemical formula.
To determine the chemical formula from percent composition, you need to convert the percent composition of each element into moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. Finally, use this ratio to write the chemical formula.
A chemical analysis and a molar mass determination are needed.
To build a compound from a chemical formula, first identify the elements present in the formula. Then, determine the ratio of each element in the compound. After that, use this information to arrange the atoms in the correct structure following the rules of chemical bonding.
The first-order reaction formula used to determine the rate of a chemical reaction is: Rate kA, where Rate is the reaction rate, k is the rate constant, and A is the concentration of the reactant.
chemical formula is an abbreviation representing the molecules of an element or a compound . The number and kind of the atoms of elements can be understood from the chemical formula . The symbol and number of atoms of each element will be indicated in the chemical formula.
The ratio of different elements present in a compound can be determined using the subscripts or coefficients in a chemical formula. These coefficients represent the relative number of each type of atom in the compound.
To write the chemical formula of a compound with polyatomic ions, first determine the charge of each ion. Then, balance the charges by crisscrossing the numerical values of the charges to determine the subscripts of each ion in the formula. Finally, write the formula with the proper subscripts for each ion to balance the charges.
To determine the empirical formula from moles in a chemical compound, you first need to find the moles of each element present in the compound. Then, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.
