Over 100 Mercy students packed the Bob Evans Restaurant in Western Hills to celebrate Mole Day on Friday, October 21. Chemists and chemistry students throughout the world celebrate the mole, which is used to represent an extremely large quantity: 6.02 times 10 to the 23rd power objects. Chemists can calculate the mass of a mole of one element, and then for another element. When the two masses are mixed, chemists know that they are mixing the same number of atoms; one mole of each type of atom. To celebrate Mole Day, Mercy chemistry students normally meet at 6:02 a.m. on October 23 for breakfast, because the 23rd is a Sunday this year the students celebrated a few days early. The celebration continued throughout the school day as students wore homemade t-shirts and hung posters alerting all students to Mole Day.
