Function
Genes decide almost everything about a living being. One or more genes can affect a specific trait. Genes may interact with an individual’s environment too and change what the gene makes.
Genes affect hundreds of internal and external factors, such as whether a person will get a particular color of eyes or what diseases they may develop.
Some diseases, such as sickle-cell anemia and Huntington’s disease, are inherited, and these are also affected by genes.
Purpose
The purpose of genes is to store information.
Each gene contains the information required to build specific proteins needed in an organism.

The molecular mass of the compound CO2 is calculate by simply taking the number of atoms of each element and multiplying it by the molar mass of the element on the periodic table.
C = 1 • 12.0 g/mol
O2 = 2 • 16.0 g/mol = 32.0 g/mol
CO2 = 12.0 + 32.0 = 44.0 g/mol.
The formula mass of CO2 is 44.0 g/mol.
