# What Is The Density Of Oxygen?

You cannot see the oxygen gas but the density of oxygen has a density. How? We will see it below in detail. Oxygen is the chemical element in the periodic table with the symbol O. The atomic number of oxygen is 8 and also is a member of the chalcogen group in the periodic table, a high nonmetal. Oxygen is also known as an oxidising agent that readily forms oxides with most elements as well as compounds. It is gas that your body needs to work properly because your cells need oxygen to make energy. Let me tell you about the density of oxygen

## What Is The Density Of Oxygen?

The density of oxygen is 1.4291 g/L at standard temperature and pressure. The increased solubility of O2 at lower temperatures has important implications on ocean life, as polar oceans support a much higher density of life due to their higher oxygen content. The molar mass of oxygen is 32 grams per mole and it is used in the calculation of density. Oxygen is a dynamic gas with a 180-degree bond angle. Many species require molecular oxygen to survive. It is used in welding, metal cutting, and rocket engine. The oxygen density in different commonly used units is given below.

The density of oxygen g/cm3 is 1.141 g/cm3, the density of oxygen kg/m3 is 1.292 kg/m3, the density of oxygen g/ml is 1.141 g/l, the density of oxygen lb/ft3 is 0.0267 lb/ft3, and the density of oxygen gas g/cm3 is 1.429 g/cm3

When you see the density of oxygen vs nitrogen, you will see the oxygen density is slightly more than the nitrogen density.

Now, you know the density of oxygen at room temperature as well as the density of oxygen at STP. Let’s learn the definition of oxygen density.

## Definition Of Density Of Oxygen

The oxygen density is defined as the mass to volume ratio of oxygen and it has a unit of g/l, kg/m3, or lb/ft3. The oxygen density varies with temperature and also with pressure. The higher the temperature, the most the molecules spread out, resulting in a lower density. As a result, warm gases rise and cool gases sink. However, the density of a gas is directly proportional to pressure. As pressure increases, with temperature constant, density increases. The definition of oxygen density in symbolic form is,

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

Or

⍴ = PMRT g/mL

Where, P = pressure = 5 atm

M = molar mass of oxygen = 32 g/mol

R = gas constant = 0.082057 L⋅atm/K⋅mol

T = Total temperature =  Tc + Tk = 27 + 273.15 K ≅ 300 K

Now that you know the formula, let’s learn how to find the oxygen density.

## How To Calculate Density Of Oxygen?

To calculate the oxygen 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.

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. For example, the density of oxygen at 20 ℃ is 1.429 g/cm3 while the density of oxygen gas at 25 ℃ is 1.11 g/L.

## FAQ

### What Is The Density Of Oxygen In G Ml?

The density of oxygen at 25C and 0.850 atm is 1.11 g/L. The density of a gas is directly proportional to its molecular weight.

### What Is The Density Of Oxygen In G Cm3?

1.429g/cm3

Density of Oxygen is 1.429g/cm3. Typical densities of various substances at atmospheric pressure.

### Is Oxygen Denser Than Water?

We know that, at room temperature the water is present at its liquid state whereas the oxygen gas is present at its gaseous state and on the basis of the fact that gases are less dense than the fluids, we can conclude that water is denser than oxygen gas at room temperature.

### What Is The Density Of Oxygen Kg M3?

The density of O2 is 16 kg/m3 at NTP .

### How Do You Find The Density Of Oxygen?

One mole of a gas at STP (0°C and 1 atm) has a volume of 22.4 L. So if we have the molar mass of the gas, divide it by 22.4 to get the density of that gas. The molar mass of O2 gas = 32 g/mol.

### What Is The Density Of O2 At 27 C?

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

### Which Is More Dense O2 Or CO2?

Molecular weight of CO2 is 44u while the molecular weight of O2 is 32u. Hence, carbon dioxide has a higher density or is heavier than oxygen.

## Conclusion

By this article, you have known lots of facts about oxygen gas and specially the density of oxygen gas. Oxygen is mostly in gas form, but with the help of some processes it can be converted into the liquid state, and the density of liquid oxygen is 1.1414 g/cm3. As you all know, oxygen is an essential gas in atmosphere and we use it for respiration, therefore, it is abundantly available in atmosphere. And the density of oxygen in air is 1.429 g/L, which is very light. Well, now you have a great understanding about the density of oxygen.
