How heavy is a mole of things


Let's compare the dozen and the mole once more.


One dozen "80g" eggs will weigh 960 grams or 0.96kg..


The mass of all the eggs on the right is 19.20kgs. How many dozen eggs are present? We answer the question by dividing the mass of all the eggs by the mass of one dozen (80g eggs). 19.20kg / 0.96kg = 20 dozen eggs.
