An instructor has a jar of sulfur that contains 16 grams. The students are asked how many sulfur atoms are in the jar. Four students give the following responses:

Arlo says, "There are 1/2 times Avogadro's number of sulfur atoms in the jar."
Bob says, "There are sixteen sulfur atoms in the jar."
Celine says, "There are two times Avogadro's number of atoms in the jar."
Delbert says, "There are sixteen times Avogardro's number of atoms in the jar."
With which, if any, of these three students do you agree:

Arlo,
Bob,
Celine,
Delbert, or
I don't think any of these students are correct
