The molecular weight of methane is 16.04. Methane, also known as marsh gas and methyl hydride, is the simplest hydrocarbon and has the chemical formula CH4. Its molecule has the shape of a tetrahedron, with the carbon atom in the center and the hydrogen atoms at the vertices.
Methane is the main component of natural gas, which makes it useful as a source of energy. It is an odorless, colorless gas at room temperature. It has a low solubility in water at 22.7 milligrams per liter, but it is soluble in organic solvents such as ethanol, diethyl ether, benzene, toluene and acetone.
