Calculating Number of Neutrons in 12.346*10^24 Moles

To calculate the number of neutrons present in 12.346*10^24 moles, we need to use Avogadro's number, which is defined as the number of atoms or molecules in one mole of a substance. The value of Avogadro's number is 6.022*10^23.

Here are the steps to calculate the number of neutrons:

1. Determine the number of atoms/molecules in 12.346*10^24 moles of the substance.

To do this, we need to multiply the number of moles by Avogadro's number:

Number of atoms/molecules = 12.346*10^24 * 6.022*10^23
= 7.427*10^48

2. Determine the number of neutrons in each atom/molecule.

The number of neutrons in an atom/molecule depends on the element or compound. To determine the number of neutrons, we need to know the atomic mass of the element or the molecular mass of the compound.

3. Multiply the number of atoms/molecules by the number of neutrons in each atom/molecule.

This will give us the total number of neutrons in 12.346*10^24 moles of the substance.

Example:

Let's take the example of carbon, which has an atomic mass of 12.01. The number of neutrons in a carbon atom is given by:

Number of neutrons = Atomic mass - Atomic number
= 12.01 - 6
= 6.01

Now, let's calculate the number of neutrons in 12.346*10^24 moles of carbon:

Number of atoms = 12.346*10^24 * 6.022*10^23
= 7.427*10^48

Number of neutrons per atom = 6.01
Total number of neutrons = 7.427*10^48 * 6.01
= 4.462*10^49

Therefore, there are 4.462*10^49 neutrons present in 12.346*10^24 moles of carbon.

Fun Video: Mole Concept

The mole concept is one of the fundamental concepts in chemistry, and it helps in understanding the relationship between the mass, number of particles, and the number of moles of a substance. The mole is defined as the amount of a substance that contains the same number of entities (atoms, molecules, ions, etc.) as there are in 12 grams of carbon-12.

A fun video on the mole concept can be found on EduRev, which explains the concept in a simple and engaging way. The video covers the following topics:

- Introduction to the mole concept
- Avogadro's number and its significance
- Calculation of the number of atoms/molecules in a given amount of substance
- Calculation of the mass of a given number of atoms/molecules
- Conversion between mass, moles, and number of particles

The video is a great resource for students who are new to the mole concept or for those who want to revise the topic in a fun and interactive way.
