# What Is The Density Of Chlorine?

Before knowing about the density of chlorine, you should know about chlorine itself. Chlorine or shortly Cl is the second lightest element of the halogen group or Group 17 of the periodic table. It is a toxic, greenish-yellow, and corrosive gas that is irritating to the eyes and to the respiratory system. Chlorine element is most significantly used as a bleach in the manufacturing of paper and cloth, but it is not limited to this only. It is also widely used to make pesticides, solvents, and rubber. Chlorine comes first to clean the drinking water and swimming pool water to kill harmful bacteria. And most significantly, it is used in your refrigerator. Let’s take a look at the density of chlorine

## What Is The Density Of Chlorine?

The density of chlorine is 3.214 g/l, which is at the standard room temperature and pressure. Similarly, the density of chlorine liquid is about 1.5625 g/cm3at standard room temperature and pressure, and the density of chlorine gas at STP is 0.3113 kg/m3. The best thing about the density is that it is not bounded to one or two units but you can measure the density in several units. So, chlorine density in different units is given below,

• The density of chlorine in g/cm3is 3.2 g/cm3
• The density of chlorine in kg/m3is 0.3113 kg/m3
• The density of chlorine g/ml is 1.468 g/ml

So, the vapor density of chlorine is 35.5. Chlorine gas density changes according to the temperature. The density of chlorine gas at 25 oC is 3.2 g/L. Similarly, the density of chlorine relative to air is 2.5 which means, the density of chlorine gas is approximately 2.5 times denser than the density of air.

Let’s know more about chlorine density including its definition.

## Definition Of Density Of Chlorine

The definition of the density of chlorine is the ratio of unit mass and unit volume. Chlorine density is directly proportional to the mass of chlorine element and inversely proportional to the volume of chlorine. Therefore, when the mass of chlorine increases then chlorine density increases and vice versa. Similarly, the volume of chlorine increases then chlorine density decreases. It can be expressed in the equation form as,

The density of Chlorine = mass of Chlorinevolume of Chlorine g/cm3

In the symbolic form,

D =    mv g/cm3

Where, d – the density of Chlorine,

v – the volume of Chlorine, and

m – the mass of Chlorine

Let me tell you how to calculate chlorine density

## How To Calculate Density Of Chlorine?

As chlorine gas is very harmful to the lungs and is a pulmonary irritant. So, you should avoid touching it with your bare hand. To calculate the density of chlorine you can use the formula of density. If you measure the mass and volume of chlorine you easily get its density by using the density formula. Let’s understand with the help of an example,

What is the density of chlorine gas at the standard temperature and pressure?

So, to calculate the density of gas you need to consider the ideal gas law which is,

PV = nRT

Where,

P – Is Pressure

R – Is universal gas constant

V – Is the volume

n – No. of moles

T –  Is the absolute temperature in Kelvin

As we are calculating the density of chlorine gas at STP, the ideal values of all parameters are fixed.

They are, P = 1.21 atm

R = 0.0821 L. atm . K-1

T = 307.9 K

Therefore, n/V = PRT

=  1.21 atm 0.821 . L . atm . (1/K . mol) x 307.9 . K

= 0.0478 . mol . L-1

So, the density of chlorine gas = 0.0478 . mol. L-1 x 70.9 g. Mol-1

= 3.40 g/L

Therefore, the density of chlorine gas is 3.40 g/L at the standard temperature and pressure.

## FAQ

### How Do You Convert Density To Cm3?

To convert between the two different units of density, we can divide or multiply by 1,000. To go from kilograms per cubic meter to grams per cubic centimeter, we divide by 1,000. And to go the other way, we multiply by 1,000.

### Why Is Density In G Ml?

Numerically, this can be expressed as the mass per unit volume and is calculated using the formula: While any units of mass and volume can be used to calculate density the most common are grams (g) and milliliters (ml). This gives density the units of grams per milliliter (g/ml).

### What Is Cm3 Same As?

A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm. One cubic centimetre corresponds to a volume of one millilitre.

### What Is The Unit Of Density?

Though the SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids, and g/L for gases.

### Is Chlorine High Density?

The density of chlorine gas is approximately 2.5 times greater than air, which will cause it to initially remain near the ground in areas with little air movement.

### Which Is Heavier Chlorine Or Oxygen?

Chlorine (CAS Registry Number 7782‐50‐5) is greenish‐yellow reactive gas with a characteristic odour similar to bleach. It is approximately three times heavier than air and therefore collects in low lying areas. It is non-combustible but enhances combustion of other materials.

### Does Liquid Chlorine Sink In Water?

Once you’ve added the chlorine, the walls and floor of the pool should be brushed to help kill off any algae and to mix the chlorine well with the water. If this step is missed, the chlorine will sink to the bottom of the pool, possibly damaging the liner.

## Conclusion

Chlorine is denser than water, therefore it sinks into the water but it makes water extremely poisonous as it is a poisonous element. It is very reactive and it is yellow-green in colour. As it is very reactive you can not keep it open in the environment. Therefore, it is suggested to keep the door of the refrigerator. As you open the door of your refrigerator, a small amount of chlorine gets evacuated and mixes in the air.
