  • BAR MEASUREMENTS || Zinc: 2.3" x 0.5" x 0.5". Aluminum 2.5" x 0.5" x 0.5". Iron 1.8" x 0.5" x 0.5". Copper 1.8" x 0.5" x 0.5"

وصف

The set of 4 metal bars (Copper, Iron, Zinc, and Aluminum) each represent one mole. This is a great way to represent the abstract concept of mole and molar mass in a visually and kinesthetically effective way.
Bar measurements:
(A) 2.3" W x 0.5" L x 0.5"H
(B) 2.5" W x 0.5" L x 0.5"H
(C) 1.8"W x 0.5" L x 0.5"H
(D) 1.8" W x 0.5" L x 0.5"H
