A coefficient in a chemical formula tells you how many molecules there are. For example, 3Co2. The number 3 which comes before the C tells you that there are 3 molecules. The coefficient is the first number. This molecules consist of 3 C atoms (1 multiplied by the coefficient 3), and 6 O atoms( 2 multiplied by the coefficient 3)
Another example:
H= one hydrogen atom
H2= one molecule made of 2 hydrogen atoms bonded together
3H20= three molecules consisting of two hydrogen atoms bonded to one oxygen atom

Where is a coefficient placed in a chemical equation?
A coefficient is placed in front of a chemical formula to indicate the number of molecules or atoms involved in the reaction. It affects the entire chemical formula that follows it in the equation.
What is understood if no coefficient is written before a formula in a chemical equation?
If no coefficient is written before a formula in a chemical equation, it is understood to have an implied coefficient of 1. This means that there is one molecule or formula unit of that particular substance involved in the reaction.
What is ment by the term coefficient in relation to a chemical reaction?
A coefficient is a number written in front of a chemical formula when balancing a chemical equation. The coefficient can represent the number of atoms, molecules, formula units, or moles of the substance.
