1. Compare the "dozens per 36 pieces" to the "moles per $$1.806 \times 10^{24}$$ atoms".  Describe any similarity in these sets of numbers.

2. Choose true (T) or false (F) for each statement about dozens, grams, and pieces.

1. Three dozen small paperclips and three dozen large paperclips have the same amount of mass.

2. Three dozen small metal nuts and three dozen large metal nuts have the same number of pieces.

3. A 15 gram sample of anything would contain the same number of pieces.

3. Choose true (T) or false (F) for each statement about moles, grams, and atoms.

1. Three moles of aluminum atoms and three moles of iron atoms have the same amount of mass.

2. Three moles of helium atoms and three moles of carbon atoms have the same number of atoms.

3. A 15 gram sample of any element would contain the same number of atoms.
