Q. One mole of CO2 contains
In order to answer the question, we need to know how many different entities one mole of CO2 contains, just as we need to know how many different bananas one dozen contains.
Let’s talk about moles. We all know that one mole is the quantity of a material that includes the same number of particles or entities that are found in precisely 12 grams of the 12C isotope. So, let’s have a look at that.
In other words, one mole of any element (or one gram of any atom) is equal to 6.02 x 1023 atoms.
Now, in the chemical complex CO2 that is being asked about, there is just one atom of carbon and two atoms of oxygen. As a result, there is one mole of carbon and two moles of oxygen in each mole of CO2.
One mole of carbon dioxide is equivalent to one mole of carbon, or 6.02 x 1023 atoms of carbon.
1 mole of carbon dioxide is equal to 2 moles of oxygen, which is equal to 2 times 6.02 times 1023 atoms of oxygen.
However, according to the dictionary definition of the mole,
1 mole of carbon dioxide is equal to 6.02 x 1023 molecules of carbon dioxide.
In this context, the number 6.02 x 1023 is referred to as Avogadro’s number (NA). It gives us an indication of the number of atoms, molecules, and other things that are included in one mole of a given material. Because the mole idea is difficult to grasp for the majority of pupils, I would ask that you kindly read it very slowly and as many times as you possibly can. You should also try to compare it with the measurements you take regularly.
