# What Is The Density Of Hydrogen?

Many of you know about the density of hydrogen and many don’t know about it. In this article, we will teach you about how to find out the hydrogen density with the help of an example. First of all, understand Hydrogen. Hydrogen is the simplest element because each atom of hydrogen has only one proton. It is the most abundant element in the universe and also harmless. It is the main component in the water along with oxygen. Also, the Sun is essentially a giant ball of hydrogen and helium gases. Naturally, hydrogen is found in its gas form but physically it can be stored in its liquid form also. Let’s know the density of hydrogen.

**What Is The Density Of Hydrogen?**

The density of hydrogen is about 0.08375 kg/m3. Hydrogen is a chemical element with atomic number 1 which means there are 1 proton and 1 electron in the stomach structure. The chemical symbol for Hydrogen is H. Hydrogen is not neutral but a very active element in chemistry, therefore, it reacts with various other elements. And when hydrogen is reacted, a new compound gets formed and it has a new density. Let’s see the densities of some hydrogen compounds. The density of hydrogen peroxide is 1.45 g/cm3. Liquid hydrogen density is 71 kg/m3 and the density of hydrogen gas is 0.00523 lb/ft3. Let’s know hydrogen density in other units too.

The density of hydrogen gas kg/m3 is 0.08375 kg/m3, the density of hydrogen in g/cm3 is 0.07 g/cm3, and the density of hydrogen gas in g/cm3 is 0.0866 g/cm3.

The density of hydrogen is calculated at standard temperature and pressure (STP). so, the density of hydrogen at STP is 0.09 g/l.

So, you know the density of hydrogen kg m3 and also in other units. Let’s understand the definition of hydrogen density in detail.

**Definition Of Density Of Hydrogen**

The density of hydrogen is defined as the ratio of the total mass of the hydrogen to the total volume of the hydrogen. The hydrogen density is completely dependent on its mass and volume. And the unit of measure for the mass of hydrogen is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams. One unified atomic mass unit is approximately the mass of one nucleon and is numerically equivalent to 1 g/mol. The definition in the symbolic form is written as,

Density of Hydrogen = pressure x molar mass of hydrogen universal gas constant x temperature g/L

Or

d = PM RT g/L

Where, d is the hydrogen density

P is the pressure on hydrogen

M is the molar mass of hydrogen

T is the temperature

R is the gas constant with value of 0.0821 L·atm/mol·K.

This is the general formula for any gas to calculate the density.

**How To Calculate Density Of Hydrogen?**

Calculating thehydrogen density gas usually involves combining the formula for density and the idea of gas law. Which is the given above. To calculate the hydrogen density go with the following steps.

- The molar mass of hydrogen is fixed, so you don’t need to calculate it.
- If you are measuring hydrogen density at room temperature, then no need to measure the temperature because room temperature is fixed which is 25°C.
- And the standard pressure is 14.696 psi or 101.325 kPa. Also, the gas constant is fixed which is 0.0821 L·atm/mol·K.
- Now, by just using the formula you can calculate the hydrogen density as,

Density of Hydrogen = pressure x molar mass of hydrogen universal gas constant x temperature g/L

d = (1.00784 x 14.696)/(0.0821 x 25)

d = 7.2161 g/L

09g/L.

**How Do You Find The Density Of Hydrogen?**

Calculating the density of a gas usually involves combining the formula for density (mass divided by volume) and the ideal gas law (PV = nRT). ρ = PM/RT, where M is molar mass.

**Why Is Hydrogen Measured In Kg?**

kilogram ($/kg)?

Because the hydrogen is delivered in a compressed gaseous form, volume measurement would not be suitable due to the dependency on pressure and temperature of the gas.

**Is Hydrogen Heavier Than Air?**

Hydrogen is another gas lighter than air; it’s even lighter than helium.

**What Is The Density Of Hydrogen Gas G Ml?**

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. Therefore, the density of hydrogen gas at STP is 0.0899 g/L.

**What Is The Density Of H2 At 0C?**

The density of hydrogen at 0C and 760 mm Hg pressure is **0.00009 g cc**.

**Why Is Hydrogen Not Dense?**

**Hydrogen has lowest atomic weight of any substance** and therefore has very low density both as a gas and a liquid. Density is measured as the amount of mass contained per unit volume.

**Conclusion**

After reading this article, you come to know that the hydrogen density is about 0.08375 kg/m3. Density is the mass per unit volume and it is an intensive property, which is mathematically defined as mass divided by volume. But, in the hydrogen or any other gas molar mass is used instead of mass. Because in chemical elements the molar mass is considered as weight or mass. With the help of this article you became well aware of how to calculate hydrogen density also. So, this was all about the density of hydrogen.
