The term "methylamine volume" is not specific enough to provide a definitive answer. However, I can provide some general information related to methylamine volume.

Methylamine is a gas at room temperature and is typically stored and transported as a compressed gas or in a solution form buy methylamine
https://forsam-medical.com/methylamine-paving-the-way-in-chemical-synthesis. The volume of methylamine would depend on the specific conditions and context in which it is being referred to.

If you are referring to the volume of pure methylamine gas, it would depend on the pressure and temperature at which it is measured. Methylamine gas can be compressed into tanks or cylinders, and the volume would be specified in terms of liters or cubic meters.

If you are referring to the volume of a solution containing methylamine, it would be specified as a percentage or concentration. For example, a 40% methylamine solution means that 40% of the solution by volume is composed of methylamine, with the remaining volume being water or another solvent.

Methylamine hydrochloride, commonly known as methylammonium chloride or methylamine HCl, is a salt formed by the reaction of methylamine (CH3NH2) with hydrochloric acid (HCl). It is a white crystalline solid that is highly soluble in water.

Methylamine hydrochloride is commonly used as a stable and easily handled form of methylamine. It has various applications in organic synthesis, pharmaceuticals, and the production of agricultural chemicals. It can serve as a building block for the synthesis of numerous compounds, including pharmaceutical intermediates, dyes, and pesticides.

The salt form of methylamine hydrochloride makes it more convenient for handling, storage, and transportation compared to pure methylamine gas or other forms. It is commercially available and often used in laboratories and industrial processes.

When dissolved in water, methylamine hydrochloride dissociates into methylammonium ions (CH3NH3+) and chloride ions (Cl-). The resulting solution can be used in various chemical reactions.
