October 23, today is National Mole Day. Every year on the 23rd of October, the day is celebrated all over the world. The date of the day has a special significance. The day is set as the day of observance, based on the number Avogadro number value. The Avogadro number value is 6.02 × 10 ^ 23. This is why it is celebrated in the United States on October 23 from 7.02 am to 6.02 pm. The time has come from 8.02 and the day, the month has been fixed from 10:23, i.e. the 23rd day of the 10th month in English.
History of National Mole Day
The National Mole Day comes from the article “The Science Teacher” in the early 1970s. Inspired by this article, Maurice Oler founded the National Mall Day Organization on May 15, 1991. Mole Day is celebrated in various schools and universities in the United States, South Africa, Australia and Canada to keep students interested in chemistry. On this day, seminars on chemistry are organized in different universities of the world. In our country too, the day is being celebrated in some universities at present. Avogadro refers to the number of atoms or molecules in a molecule.
National Mole Day commemorates the hypothesis of Amadeo Avogadro. He was born in 1776 and was one of the famous founders of physical chemistry. He didn’t really get the reward he deserved until his hypothesis was put forward fifty years later and after his death. He is known for his hypothesis called “Avogadro’s Law”, in which the pressure and temperature are fixed, and an equal volume of gas has the same number of molecules.
National Mole Day Activities
Understanding molecular science
Avogadro’s numbers are complex enough that it might leave you puzzled. Learn more about his hypothesis by reading his hypothesis and his life. Understand his carelessness in the laboratory, the lack of backup of his experimental results, and why his quirky and introverted ways did not receive enough attention while he was alive.
Create a mole story
Appeal to all students, creativity is the key to this holiday. Try to write a short play to show your understanding of National Mole Day. Write stories, compose poems or songs, and make sure to add mole jokes. There is a lot of mole humor on the Internet, don’t be shy. How many puns can you think of when doing this experiment?
Baking a mole
Measure, estimate, and solve problems. Make edible mole foods such as biscuits, cakes, cupcakes, or chocolate cakes. If you are really smart, you can use mole measurements, such as 1 mole of sugar, etc. Remember, moles can be converted to grams.
Some Facts about National Mole Day
• Mole, also spelled mol, is the standard scientific unit for measuring a large number of tiny substances (such as atoms, molecules, or other designated particles) in chemistry.
• This mole comes from the 18th century Italian researcher Amedeo Avogadro, his full name is Lorenzo Romano Amedeo Carlo Avogadro di Queregna e di Cerreto.
• The mole is a unit of measurement used in chemistry and other related fields such as biochemistry and biophysics.
• It is one of the recognized measurement units in the International System of Units. It is identified by the Avogadro constant and represented by the abbreviation “mol”.
• Mole Day was proposed in an article by The Science Teacher in the mid-1980s. Inspired by this article, Maurice Oehler, a chemistry teacher (now retired) in Prairie du Chien, Wisconsin, founded the National Mole Day Foundation in 1991.
• If there is a grain of rice, all land areas in the world will be covered by rice, with a depth of approximately 75 meters.
• In chemistry, the mole is a more advantageous standard unit than trying to quantify mass or volume, especially in chemical equations.
• The concept of molecular mass further simplifies the description in measurement. Molecular mass means that the mass of one mole of a substance (in grams) is equal to the molecular mass.
• Therefore, one mole of a substance is equivalent to the molecular mass of a similar substance. The development history of Moore as a standard measurement unit for calculating the basic entities contained in the matter can be traced back to the first relative atomic mass table created by John Dalton in 1805.
• Later, Jons Jacob Berzelius redefines the relative atomic mass with greater accuracy.
