Why is 23 October celebrated as Mole Day

Mole day is celebrated on 23 october between 6:02AM and 6:02PM
Friends, today I tell you about a interesting day name "Mole Day". Interesting, because the timing and date represents a entire scientific number.
OK, let's start. 

Mole day is celebrated on October 23, between 6:02AM and 6:02PM. It is a day, generally celebrated among scientific community especially, Chemist, Chemistry students and chemistry enthusiasts.

Friends, first I tell you what is mole? and then I describe why this date is chosen for Mole day. 

What is Mole?

In Science, mole is a unit of substance like Dozen ( a set of twelve).
e.g. I can say,
"A dozen pens." , "One mole pens." 

A dozen = 12 pieces
1 mole = 6.02214076 ✕ 1023 pieces 

The number 6.02214076 ✕ 1023 is known as Avogadro's number. 

In fact, we don't say one mole pens because one mole pen is huge number ( but we can say one mole pens).
The unit "mole" is used in Chemistry.
Generally, in Chemistry , we frequently use the terms:
"1 mole H (Hydrogen)."
"1 mole molecules." etc. 

Why is October 23 chosen as Mole Day?

Why there is time boundation i.e. 6:02AM-6:02PM? 

OK, I am answering all the questions.
We have already learnt that,
1mole =6.02214076 ✕ 1023 units of substance. 

Generally, we don't say this big number, rather we say,
1 mole= 6.02 ✕ 1023 unit of substance. 

In USA, people write the date as mm-dd-yyyy.
So, in USA format,
23rd October is written as 10-23. 


Mole Day is celebrated between 6:02AM and 6.02PM on October 23. So, it can be written as
6:02AM to 6:02PM on 10-23.
Actually, it looks closer to  6.02 ✕ 1023(1 mole). 

Hence, 23rd October and that specific time frame is chosen. 


Thank You for reading.

KNOW ABOUT BASIC ELECTRICAL AND ELECTRONIC DEVICES

Nowadays, we are familiar with the, electricity and various electrical instruments. There are many things  e.g light, fan, TV, refrigerator,switch,fuse etc. in our house. We use this instruments. But we frequently listen some terms and devices name viz. voltage, current, AC Current, DC Current, resistor, transformer, capacitor, LED, inductor etc . which we don't use these directly. But, amazing fact is that, the instruments which we daily use, are made of these(resistor, capacitor etc.).  Let's discuss these. Here, I don't discuss these so deeply. What is Voltage? and  What is Current? Voltage( Potential difference) represents the force. And Current represents the flow of electrons in the circuit. We (who are the basic users or novice) need not know much about this. It is a image of mobile charger.See what is written as input and output The unit of voltage is volt ( v ) and current is ampere ( A ). 1mA=(1/1000) A You obviously heard the term w

FUNCTION OF BASS, TREBLE, VOLUME OPTION IN AN AMPLIFIER

-

Bass and Treble options are used to regulate the sound on the basis of frequency.  Generally a audio amplifier has 3 main controlling options. (i) Volume or Master  (ii) Bass (iii) Treble Volume : When we increase Volume the loudness of the audio is increased. In frequency level, the amplitude of all the frequencies are increased.  Similarly, when we decrease Volume, the loudness is decreased i.e. amplitude of all the frequencies are decreased. Bass : When we increase Bass, the loudness of only lower frequencies are increased i.e. amplitude of the lower frequencies are increased. When we decrease Bass, the loudness of only lower frequencies are decreased i.e. amplitude of the lower frequencies are decreased. Treble : When we increase / decrease the Treble, the loudness of the sound of only higher frequencies are increased / decreased. Now the main questions is that what do lower and higher frequencies mean ? We know that human beings able to hear in the fre

MATTER AND ITS STATES (PHASE)

-

What is Matter: Matter is anything that has mass and occupy space. Example: wood,water,Oxygen etc. All tangible things are made of matter. How many states (phases) can a matter have in nature: There are normally 3 states. Solid, liquid and gas. There exists another one, named Plasma state. In this post, this state is not described.  Every matter can be converted from any state to any state. Suppose, water. Water can be got as solid, liquid, or gas. We know solid form of water is called ice, liquid form is water , and gaseous form is  water vapor.    How can the state of matter be changed: The changing of the state of matter is known as Phase change of matter. We can change the state of a matter Varying the Pressure Varying the Temperature  1.Changing of phase by varying Pressure: Increasing the pressure, gas can be converted into liquid and then solid. Similarly, solid can be converted into liquid and then gas. Match lighter You may
