Density Of O2

What Is The Density Of O2? 

You may be surprised after hearing about the density of O2. Because oxygen or O2 is a gas and is a very light element. Therefore, it is interesting to measure the density of oxygen. If you take an iron or other metal in your hands, then you will fill some weight. But, you can not feel even a minute of weight, when you take O2 in your hand. And the density depends on the weight or mass of the object. Therefore, oxygen has very less density and it is found in gas form at room temperature. It is lightweight, so it never stops in one place and it is always moving. Below, we will give you the formula to calculate the O2 density. Well, without extending further let’s learn about the density of O2 in detail.

What Is The Density Of O2? 

The density of O2 is 1.4291 g/L, which is denser than the density of air. Air and O2 are respectively 14.1 and 16 times as hickey as hydrogen gas. The density of any gas depends upon the temperature. The higher the temperature, the more the molecules are spread out and the lower the density. The result is that cool gases sink and warm gases rise. The same concept helps to explain the weather resulting in high and low pressure. High pressure means high-density, cooler, sinking air. Low pressure means low-density, warmer, rising air.   

You can measure the density of oxygen in several other units. Here is the density of oxygen in various units, 

  • The density of O2 kg/m3 is 1.292 kg/m3
  • The density of O2 at STP is 1.4291 g/L
  • The density of O2 in g ml is 1.141 g/ml 
  • The density of O2 in air is 1.4291 g/L 
  • The density of Oxygen g/cm3 is 1.141 g/cm3
  • The density of O2 at 1 ATM and 15 c is 1.225 kg/m3 

Well, you understood the density of O2 gas. Let’s know how to measure and calculate it. 

Definition Of Density Of O2 

The density of O2 is defined as the amount of O2 present per cubic space or the ratio of the mass to the volume of the O2. in simple language, the density of O2 is nothing but the ratio of mass and volume. The O2 density is dependent on the factors like temperature, pressure, mass, volume, etc. O2 density is inversely proportional to volume and temperature, which means when volume or temperature increases the density decreases and vice versa. Similarly, the O2 density is directly proportional to the mass and the pressure, which means when mass or pressure increases the density also increases and vice versa. 

The definition of O2 density can be expressed in the equation form as, 

The density of O2 = mass of O2volume of O2 g/cm3 

In the symbolic form, 

               D =    mv g/cm3 

Where, d – the O2 density, 

             v – the volume of O2, and 

            m – the mass of O2 

How To Calculate Density Of O2? 

Calculating the density of oxygen is very easy as there is already a formula derived for it. To calculate the O2 density, you just need to put the values of the constant, including the ideal gas constant, room temperature value, and standard pressure value, in the formula and you will get the answer. 

The density of Oxygen = pressure constant x molar mass of oxygen temperature x universal gas constant g/mL 

 Now, you need to insert the values you know, 

                              ⍴ = 5 atm × 32 g/mol0.082057 L⋅atm/K⋅mol ×300 K g/L 

                             ⍴  =  160/24.69 g/L                         

                             ⍴  = 6.5 g/L 

So, oxygen gas density at 5 atm is 6.5 g/L. But, you will see that oxygen has different densities at different temperatures and pressures. Like, The density of oxygen at 20 ℃ is 1.429 g/cm3 while the density of oxygen gas at 25 ℃ is 1.11 g/L. 

For Example, 

Let’s take an example. 

What is the density of O2 at room temperature and standard pressure? 

As you all know, at room temperature, 

the Molar mass of O2 – 32g/mol

Volume of the gas at NTP – 22.4 L/mol 

So, by using the formula, 

The density of Oxygen = pressure constant x molar mass of oxygen temperature x universal gas constant g/mL 

Noe, by putting these values in the formula,                         

                             ⍴  =  (32 g/mol)/22.4 L/mol                         

                             ⍴  = 1.482 g/L

FAQ

What Is The Weight Of Oxygen Gas?

Oxygen is an element with atomic symbol O, atomic number 8, and atomic weight 16.

What Is The Density Of Air And O2?

The density of air is 14.4 and that of oxygen is 16.0.

What Is The Density Of Oxygen At 2?

On substituting these values we get, ρ=2. 6g/L.

What Is The Density Of Co2 And O2?

In reality, oxygen gas has a density of 1.429 grams/liter at the so-called standard pressure and temperature (basically room temperature and atmospheric pressure) while carbon dioxide has a density of 1.977 grams/liter. If you do the math, you will find that carbon dioxide is 1.383 times as heavy as oxygen.

Is O2 Denser Than H2?

oxygen gas is more heavier than hydrogen gas,as for gases density depends upon the molar mass.So,H2 has more molar mass of 2g/mole than that of oxygen O2 is 32. thus hydrogen gas is 16 times lighter than oxygen gas.

Conclusion 

By reading this article, you come across the density of O2 at STP. Why is the density of a gas important? The density of a gas is very important because gases like oxygen, helium, etc., have various applications based on their densities. For example, the applications are Helium balloons, Hydrogen balloons, carbon dioxide, and floating flame. Oxygen plays a key role in respiration, the energy-producing chemistry that derives the metabolism of most living things. We, humans, along with many other living beings, need oxygen in the air we breathe to stay alive. So, for all these purposes, the density of oxygen is critically important.
