A variable is assigned to represent an unknown quantity.
Ø In chemistry, algebra can be used to calculate the quantity of a substance required in an experiment. Also, it is used to calculate the quantity of various substances formed in an experiment. Problems of Mole concept are soved on this basis only.
VARIABLE. When this variable has a fixed number assigned to it and does not change, it is called a "fixed variable".

The quantity being tested in a chemistry experiment is typically referred to as the independent variable. This is the variable that the chemist deliberately changes or manipulates to observe how it affects other variables in the experiment. The dependent variable, on the other hand, is the variable that is being measured or observed and is influenced by the changes in the independent variable.
A scalar quantity is a quantity that is ignorant of direction. Scalars have only magnitude, such as temperature or distance, and do not have associated direction information.
