Delving into the Molecular Structure and Composition of Ethene
Ethene is composed of two carbon atoms and four hydrogen atoms, forming a double bond between the carbons. Its molecular formula is C2H4, indicating the presence of two carbon atoms and four hydrogen atoms in its structure. The molecular mass of ethene can be calculated by adding the atomic masses of its constituent atoms.
Calculating the Molecular Mass of Ethene
Atomic masses are provided by the International Union of Pure and Applied Chemistry (IUPAC). According to IUPAC, the atomic mass of carbon is approximately 12.01 atomic mass units (amu), and the atomic mass of hydrogen is approximately 1.008 amu.
To calculate the molecular mass of ethene, we simply add the atomic masses of two carbon atoms and four hydrogen atoms:
M(C2H4) = 2(12.01 amu) + 4(1.008 amu) = 28.054 amu
Therefore, the molecular mass of ethene is approximately 28.054 amu.
