What Is The Density Of Methanol? 

density of methanol

Are you looking for the density of methanol, right? Then you should read this article. Understand methanol first. So, methanol is a toxic alcohol that is used industrially as a solvent, pesticide, and alternative fuel source. It is found naturally in plants, humans, and animals also. Foods including fresh fruits and vegetables, fruits juices, fermented beverages, and diet soft drinks containing aspartame are the fundamental sources of methanol in the human body. Most methanol poisoningscases, drinking beverages contaminated with methanol or from drinking methanol-containing products is a cause. Inhalation of high concentration of methanol vapour and absorption of methanol through the skin lead to producing toxic effects. Let us start with the density of methanol.  

What Is The Density Of Methanol?

The density of methanol is 792 kg/m3, which is at room temperature and pressure or ATP. The methanol density describes the relation between its mass and its volume. 

The methanol density is dependent on the temperature. Let’s explore the effect of different temperature conditions of methanol’s density by knowing the density of methanol at different temperatures.so, the density of ethanol at 20 c is 791 g/l, the density of methanol at 2.0 c is 808.2 g/l, and the density of methanol 25 c is 785.4 g/k. As we can see, the methanol density decreases with an increase in temperature and greatly decreases with a change in state from solid to liquid. 

Let us see the methanol density in other units also. The density of methanol mg/ml is, the density of methanol g/cm3 is 0.79 g/cm3, the density of methanol kg/l is 0.793 kg/l, the density of methanol g/l is 791.4 g/l, and the density of methanol g/ml is 0.791 g/ml. 

Now, you have an idea about the density of methanol g ml, the density of methanol g cm3, and in other units too. Let me tell you the definition of the methanol density in detail. 

Definition Of Density Of Methanol

The density of methanol is defined as the mass of methanol per unit volume of methanol. It describes the relation between mass and volume of methanol. Mass means amount of matter and volume means space it occupies in 3 dimensions. 

The relative density of methanol, which is the density when compared to water which has a density of 1000 g/cm3, is 0.79. This means, methanol is less dense than water and would float on top of the water. On the other side its relative vapour density, the density of methanol in vapour form compared to that of air, is 1.11. This means, methanol is denser than air and so the vapours would sink to lower levels in the air. 

The definition of methanol density can be expressed in the equation form as, 

Density of methanol = Mass of methanol/Volume of methanol g/cm3 

In the symbolic form, 

                           D = mv g/cm3 

Where, d – the density of methanol, 

            m – mass of the methanol, and 

             v – the volume of methanol  

How To Calculate Density Of Methanol?

To calculate the density of methanol, you would actually need to measure the mass and volume of methanol. Let us how to calculate it, 

  1. Take a container with a fixed volume and pour the methanol in it. 
  2. Measure the weight of the container filled with methanol and subtract the weight of the empty container from the final weight. It will give you the mass of methanol. 
  3. You already know the volume because of the fixed volume container. 
  4. Now, divide the mass by volume, you will get the volume of methanol density.  

To understand it in more depth, consider the example given below. 

If the 17.15 moles of methanol are poured in 1.0 litres of pure methanol, then what will be the density of methanol? 

By using density formula, 

 D = mv g/cm3 

 Given, volume of methanol = 1.0 L = 1000 mL 

            Mass of methanol = 17.15 mols = 21.15 x 46 grams = 972.9 grams 

So, density of methanol = 972.9/1000 

                                   = 0.972 g/mL 

Let’s find out the densities by visiting Denseme


What Is The Density Of Pure Methanol?

The density of methanol is 791.80 kg/m³ and molar mass is 32.04g/mol.

What Is The Density Of Methanol In Kg Per Cubic Meter?

Density of methanol [CH3OH]
Methanol weighs 0.7914 gram per cubic centimeter or 791.4 kilogram per cubic meter, i.e. density of methanol is equal to 791.4 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure.

Is Liquid Methanol Heavier Than Water?

Liquid agent is lighter than water.

Does Methanol Density Change With Temperature?

The density of liquid methanol is nearly the same for all pressures up to 100 bara and 25 °C (77°F), and the density of the liquid at equilibrium pressure can be used for most practical purposes.

What Is The Main Use Of Methanol?

Methanol is primarily used as an industrial solvent to help create inks, resins, adhesives, and dyes. It is also used as a solvent in the manufacture of important pharmaceutical ingredients and products such as cholesterol, streptomycin, vitamins and hormones.


While reading this article you gained a lot of knowledge regarding the methanol’s density and its calculations. Methanol is a simple alcohol containing a methyl group bonded to an alcohol group. The chemical structure of methanol contains a carbon atom bonded with three hydrogen atoms and one oxygen atom. The same oxygen atom is again coned with one hydrogen atom. You need to be very causitin while handling methanol, because it is considered to be highly flammable and volatile. Keep this one aspect in mind regarding volatility. The more volatile the substance is, the lower its boiling point will be. Now, you know all about the density of methanol.
