GRAMS METHOD Meaning and
Definition
-
The "grams method" refers to a technique used in elementary chemistry for performing stoichiometric calculations and finding the amounts of reactants and products in a chemical reaction. It is named after the Russian chemist Mikhail Vasilyevich Grains, who developed and popularized this method in the 19th century.
In this method, the quantities of reactants and products are determined by converting them into grams. The first step involves writing a balanced chemical equation to represent the reaction. Then, the molar masses of all the substances involved are determined and converted into grams.
To calculate the amount of a particular substance, one must know the amount of another substance involved in the reaction. This information is usually provided in the problem or can be determined using specified data. The ratio of the amount of the known substance to the unknown substance, based on the balanced equation, is used as a conversion factor.
Using conversion factors, the given amount of one substance is converted to moles, and then to grams. This process is repeated for the other substance, allowing the determination of the desired quantity. The grams method is typically employed for quantitative analysis and to solve problems related to limiting reactants, percent yield, and stoichiometry in chemical reactions.
The grams method is widely used in introductory chemistry courses to develop a deeper understanding of chemical reactions and the relationship between reactants and products. It provides a systematic approach to calculate the quantities of substances involved, enabling scientists to accurately determine the amount of reactants needed or the amount of product produced in a given reaction.
Etymology of GRAMS METHOD
The term "Gram's method" originates from the name of the Danish mathematician and engineer Jørgen Pedersen Gram.
