So the mass of an average carbon atom is 12 amu and the mass of a mole of carbon atoms is 12 g. The activity began with a set of data that showed when there are equal numbers of quail eggs and chicken eggs the ratio by mass is 1:16. Thanksgiving Break!!! POGIL Activities for High School Chemistry by Laura Trout). My students quickly realize that not only do I like to make things by hand, but I also enjoy bad jokes! Do you have a great mole activity? Now the emphasis was on a simple question. This is the value of the molar mass. Mole art | | University of Waterloo. As an example, they had to place an amount of lentils on the scale to get to one gram. Safety Exam/Debrief. There are twice that many atoms of fluorine in 38.
This is the "relative" mass of the white limas as compared to the lentils. I love the element of fun that mole art brings to my teaching environment.
