We all have heard about H2 and its importance. But not all know the density of H2, which is important to know. Therefore, taking into consideration we are here to give you all about the H2’s density and also provide a formula to calculate it. H2 means Hydrogen, which can be used to power vehicles, generate electricity, power the industry, and heat our homes and businesses. One of the very important facts about hydrogen is, without hydrogen, there will be no water. You know, the chemical formula of water is, H2O, and in this H2, is nothing but Hydrogen. Without having more discussion let’s know the density of H2.
What Is The Density Of H2?
The density of h2 is 0.0899 g/L, which is at the standard temperature and pressure or STP. Since gases like hydrogen, all occupy the same volume on a per-mile basis, the density of a particular gas is dependent on its molar mass. The density of hydrogen is directly proportional to the temperature and inversely proportional to the pressure. This means when temperature increases the density also increases and when temperature decreases the density also decreases. Similarly, when pressure increases the density decreases, and when pressure decreases the density decreases.
The density of hydrogen can be measured in different units. Here are the different densities of the hydrogen atoms.
- The density of H2 at STP is 0899 g/L
- The density of H2 in g/l is 0899 g/L
- The energy density of H2 is 0899 g/L
- The density of H2 gas in kg/m3 is 0.09 kg/m3
- The density of hydrogen gas at STP in kg/m3 is 0.09 kg/m3
- The density of hydrogen gas in g/cm3 is 0.0009 g/cm3
- The density of H2 at 25 C is 0899 g/L
- The density of H2 at room temperature is 0899 g/L
- The vapor density of H2 is 0899 g/L
Definition Of Density Of H2
The density of H2 is defined as the value of its mass divided by the volume of the same. In other words, the number of Hydrogen atoms compatible with a cubic meter area or space. H2 density is directly proportional to the mass of H2 and inversely proportional to the volume of H2. This means, as mass increases, the density alo increases and vice versa. While, as the volume of H2 increases the density of H2 decreases and vice versa. The definition of H2 is can be expressed in the equation form as,
The density of H2 = mass of H2volume of H2 g/cm3
In the symbolic form,
D = mv g/cm3
Where, d – the H2 density,
v – the volume of H2, and
m – the mass of H2
How To Calculate Density Of H2?
To calculate the density of H2 you need to know the formula. We have given it above. First of all, you need to measure the mass as well as the volume of the H2 atom, then you can calculate its density. Below we have mentioned an example, have a look.
What is the density of H2 at STP?
Well, STP conditions are standard temperature and pressure, which means the values at STP are 0 0C temperature and 1 bar pressure.
To calculate the density, we need a molar mass of Hydrogen and it is 2 g. Now, for mass and volume, we will use the Ideal gas equation and take out both mass and volume.
The ideal gas equation is, PV = n x R x T
P = pressure = 1 atm
M = molar mass of H2 = 2 g
R = gas constant = 0.082057 L⋅atm/K⋅mol
T = temperature = 273.15 K
So, 1 x V = (m/2) x 0.082 x 273.15
V = (m/2) x 0.082 x 273.15
By keeping this value in the formula, the mass will get canceled out and we will get the density as,
Density of H2 = m/((m/2) x 0.082 x 273.15)
= 2/(0.081 x 273.15)
= 0.09 g/L
Hence the density of H2 at STP is 0.09 g/L.

How Do You Find The Density Of H2?
Hydrogen gas is diatomic and has the formula H2 and a molar mass of 2.016 g/mol. d=(1.0atm)(2.016g/mol)(0.08206Latm/molK)(273.15K) d = ( 1.0 a t m ) ( 2.016 g / m o l ) ( 0.08206 L a t m / m o l K ) ( 273.15 K ) = 0.0899 g/L.
What Is The Density Of Liquid H2?
Hydrogen turns into a liquid when it is cooled to a temperature below -252,87 °C. At -252.87°C and 1.013 bar, liquid hydrogen has a density of close to 71 kg/m3.
What Is The Density Of H2 At 0C?
The density of hydrogen at 0C and 760 mm Hg pressure is 0.00009 g cc.
How Do I Calculate Density?
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
How Much Is 1kg Of Hydrogen?
Hydrogen Conversion Information
423 standard cubic feet (scf) = 1 kilogram (kg) of hydrogen. It takes 2.3 gallons of water to create 1 kg of hydrogen.
Hydrogen or H2 also has a very great role in health, it is said to increase energy, reduce inflammation, and reduce recovery times after workouts. Also, it acts as an antioxidant preventing organ and cell damage. It will also support and strengthen your natural antioxidant system. H2’s energy content by volume is low, this makes storing hydrogen a challenge because it requires high pressure, low temperature, or chemical processes to be stored compactlyand you should know the density of H2.
