Imagine you have a mole of jellybeans. How large would this quantity be?

• Enough to fill a large house

• Enough to cover a small country

• As large as planet Earth

A mole of sulfur atoms can fit into a small dish, while a mole of jellybeans is as large as Earth. What is the primary reason for this difference in volume?

• Sulfur atoms are much denser than jellybeans

• Sulfur atoms are significantly smaller than jellybeans

• A mole of sulfur atoms contains fewer particles than a mole of jellybeans

• The shape of sulfur atoms allows them to pack more efficiently
