What's a Mole for?
Sheryl Dominic
Deering High School, 370 Stevens Avenue, Portland, ME 04103
Cover
April 1996
Vol. 73 No. 4
p. 309
Abstract
A classroom competition for guessing the number of jelly beans in a jar of candy is used to help students understand the premise of the mole concept: counting particles by weighing. Students calculate the number of jelly beans in the jar of candy by weighing them all and then dividing this weight by the average weight of a single jelly bean. Then, they extend this process to understand how the mole concept enables chemists to count particles by weighing.
