What Is The Density Of Chromium? 

The density of chromium is one of the important properties of chromium element. Chromium is an element with an atomic number of 24 and an atomic weight is 51.996. The chemical formula of chromium or chromium symbol is Cr. This element is mainly used to harden steel, manufacture stainless steel, and produce several alloys. Chrome plating can be used to give steel a shiny mirror finish. Chrome car and truck parts like bumpers were once very common. A plate of chromed plastic, often used for plumbing, will also work. Chromium is a hard, silvery metal with a bluish tinge. Without having more discussion let’s move to the density of chromium.       

What Is The Density Of Chromium? 

The density of chromium is 7.2 g/cm3, which is at standard temperature and pressure. The atomic density of chromium is 7.2 g/cm3, the density of chromium oxide is 5.22 g/cm3, the density of chromium plating is 7.2 g/cm3, and the density of chromium unit cell is 7.2 g/cm3. You can measure chromium’s density in different units. Here is chromium’s density given in different units, 

  • The density of chromium g/mm3 is 0.0072 g/mm3 
  • The density of chromium in kg/m3 is 2162 kg/m3 
  • The density of chromium in g/ml is 7.19 g/mL 
  • The density of chromium g/cm3 is 7.2 g/cm3 

Chromium density changes with the temperature. This means when temperature increases the density decreases and when temperature decreases, the density decreases. Now, you know the density of chromium metal, let’s learn how to measure the density of chromium. 

Definition Of Density Of Chromium 

The density of chromium is defined as the ratio of mass and volume of chromium. The density of Cr is directly proportional to the mass and inversely proportional to the volume. The unit of measure for mass is the atomic mass unit or amu. One atomic mass unit is equal to 1.66 x 10^-24 grams. One single atomic mass unit is approximately equal to the mass of one nucleon, numerically 1 g/mol. The atomic mass number is determined, especially the atomic mass of atoms, the mass number is different for each different isotope of a chemical element. The definition of chromium’s density can be expressed in the equation form as, 

The density of Chromium = mass of Chromiumvolume of Chromium g/cm3 

In the symbolic form, 

               D =    mv g/cm3 

Where, d – the Chromium density, 

              v – the volume of Chromium, and 

             m – the mass of Chromium 

How To Calculate Density Of Chromium? 

Calculating the Chromium’s density is easy because Chromium is not harmful and also not volatile. To calculate the density, just need to follow the procedure given below. 

  1. Take a small piece of Chromium and measure its weight. 
  2. To measure its weight, just hook it below the balance by using a light-weighted thread.  
  3. Now, you have a mass of Chromium, and you have to find its volume. So, to calculate volume use the water displacement method. 
  4. Take a beaker and fill it with water and then immerse the same Chromium piece into the water. Now, measure the volume of the beaker and you will get the volume of Chromium. 
  5. Now, divide the mass by volume you will get the Chromium’s density. 

Let’s have an example to understand the formula. 

What is the density of chromium at the standard temperature and pressure? 

By using the formula, 

The density of Chromium = mass of Chromiumvolume of Chromium 

The molecular weight or the mass of chromium is 52 g mol-1 

a = 289 pm = 289 x 10-10 cm 

N = 6.02 x 1023 mol-1 

Now, putting the values in the formula, then you will get, 

Density of chromium = (52)/((289 x 10-10)3 x 6.023 x 1023 

                                     = 7.2 g/cm3

What Is The Density Of Chromium In Kg M3?

It was established that the density values are decreased from 7750 to 7320 kg/m3 at considered chromium concentration range. These alloys have the density values above optimal one (5000–7000 kg/m3) and they correspond to a heavy alloys group.

Is Chromium A Strongest Metal?

With a rating of 8.5 on the Moh’s hardness scale, chromium is the hardest metal on the planet (easily outclassing titanium, which is rated at a mere 6. Only boron and diamond sit above chromium on this scale, with ratings of 9.5 and 10 respectively.

How Do You Find Density In G Cm?

Grams per centimeter cubed is equivalent to grams per milliliter (g/cm3 = g/mL). To solve for density, simply follow the equation 1.5. 1. For example, if you had a metal cube with mass 7.0 g and volume 5.0 cm3, the density would be ρ=7g5cm3=1.4g/cm3.

What Is The Chromium Weight?

The atomic weight of chromium element is. 9961 u .

What Is The Density Of Chromium In G Ml?

The density of chromium is 7.19gmL.


In this article, we have given you the density of chromium as well as how to find it by using a formula. Chromium is a lustrous, hard, brittle metal and its color is silver-grey and it can be highly polished. It does not discolor in the air but ignites when heated to form green chromium oxide. Chromium is unstable to oxygen and immediately forms a thin oxide layer that is impervious to oxygen and protects the underlying metal. Chromium’s popular uses are in alloys such as stainless steel, chrome plating, and in metal-ceramic. Chromium plating was once widely used to give steel a polished silvery mirror coating. Now you know everything about the density of chromium
