Answer: HOPE THIS HELPED! ;D :P
The study of the mass relationships of element compounds is known as composition stoichiometry
Explanation:
In this exercise we have to use the knowledge of chemistry to explain the study of mass between elements, as follows:
The study of the mass relationships of element compounds is known as composition stoichiometry.
What is stoichiometry and what is it for ?
Stoichiometry studies the relationships between reactants and products in chemical reactions. Stoichiometry allows us to calculate the exact amount of reactants that are needed to obtain a given amount of product in a chemical reaction.
