Simple calculations using chemical equations

The study of the chemical changes of substances often involves the calculation of quantities. According to the calculation of chemical equations, the changes of substances can be studied from the aspect of quantity. For example, what is the maximum number of products that can be produced with a given amount of raw material? What is the minimum amount of raw materials required to prepare a certain amount of product? etc. Through calculation, the planning of production can be strengthened, and it is conducive to the rational use of resources.

It should be noted that in actual production and scientific research, many raw materials used are impure, and impurities should be taken into account when calculating, which will be learned in future courses.

After learning this subject, you should know

According to the mass of one reactant or product actually participating in the reaction, the mass of other reactants or products can be calculated.
