What is mole day? I had no idea until last week in my Chemistry class.

Mole day is celebrated annually on October 23 from 6:02 a.m. to 6:02 p.m. Mole Day is to celebrate Avogadro's Number (6.02 x 10^23), which is a basic measuring unit in chemistry. Mole Day was created to promote interest in chemistry. Schools throughout the United States and around the world celebrate Mole Day with various activities related to chemistry and/or moles.

To celebrate this year's mole day, I wrote a letter to Avogadro, which includes thanks to him for making a unit so useful in chemistry but at the same time complaining to him about all the mole calculations we have to do in chemistry class.

Amedeo Avogadro was a Italian scientist who made Avogadro's law, which states that equal volumes of gases under the same conditions of temperature and pressure will contain equal numbers of molecules. A mole is now the SI unit, international system of units, for substances. It might not make sense at first if when you learn that a mole is a unit. But just think of moles as a "chemist's dozen". Just as 12 eggs is a dozen eggs, 6.02 × 10²³eggs is a mole of eggs. 6.02 × 10²³ molecules of oxygen is a mole of oxygen.

There are different themes for mole day each year and this year's theme is:

The Periodic Table of the EleMOLEments

Since the theme is a pun with moles. I have some puns to celebrate mole day! Hope everyone loves puns as much as I do!

1. What do you call a 10th grader who is taking chemistry? - Sophomole (What I am right now!)

2. What kind of fruit did Avogadro eat in the summer? - Watermolens

3. What kind of test do chemistry students like the best? - Mole-tiple choices

4. What does Avogadro put in his hot chocolate? - Marsh-mole-ows

5.What did one mole say to the other? - "We make great chemistry together"

6. What did Avogadro teach his students in math class? - moletiplication

7. How do moles finance their homes? - With a molergage

8. What's the mole's favorite college football team? - The Florida State Semimoles
