Mole
MOLE: A very large unit that measures quantity
Here’s an analogy to help you understand the idea of a mole. Units of measurement:
a. Dozen: If a dozen eggs is 12 eggs, then two dozen eggs are 24 eggs (12 x 2 = 24).
b. Mole: If one mole weighs 44 grams, then two moles are 88 grams (44 x 2= 88).
• MOLAR MASS/ GRAM-ATOMIC MASS: The mass of one mole of an element
The molar mass of one CO2 = mass of 1 mole of CO2
