On Mole Day, we celebrate the incredible number that bridges the microscopic realm of atoms and molecules to the grand scale of the universe. Test your understanding and see how well you know Avogadro’s constant and the concept of the mole with our daily quiz!
Visual Question: What’s the connection between this lunar crater and Mole Day?
(Image of a lunar crater would appear here)
Answer: This lunar crater is named after the Italian scientist Amedeo Avogadro, whose work is central to Mole Day celebrations.
Question 1: What is the exact date and time when Mole Day is traditionally celebrated?
Answer: Mole Day is celebrated annually on October 23rd, from 6:02 a.m. to 6:02 p.m., referencing the first digits of Avogadro’s number.
Question 2: What is the numerical value of the constant commemorated on Mole Day, and what does it represent?
Answer: The numerical value is 6.02 × 10²³, and it represents the number of elementary entities (like atoms or molecules) in one mole of a substance.
Question 3: Who is the scientist after whom this significant constant is named, and what key hypothesis did he propose in 1811?
Answer: The constant is named after Amedeo Avogadro. In 1811, he proposed that equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules.
Question 4: In chemistry, what exactly is a ‘mole’?
Answer: In chemistry, a mole is a standard unit used to measure the amount of a substance. It’s defined as containing approximately 6.02 × 10²³ particles, whether they are atoms, molecules, ions, or other elementary entities.
Question 5: Which influential Italian scientist played a crucial role in reviving Avogadro’s hypothesis at the Karlsruhe Congress in 1860, ensuring its recognition in the scientific community?
Answer: Stanislao Cannizzaro was the Italian scientist who effectively revived and championed Avogadro’s hypothesis at the Karlsruhe Congress in 1860.
