Answer:
Molecules to moles is a one step conversion.
Explanation:
You need to understand the definition of a mole. It's basically 6.022x10^23 molecules, atoms, pencils, people, etc. it's like a dozen but a giant number. Having this in mind: 1mole=6.022x10^23
So it turns into a stoichiometry problem:
9.3x10^24 molecules (1 mole / 6.022 x 10^23 molecules) = your answer in moles.
