Discussion Overview

The discussion revolves around understanding the concept of moles, specifically in relation to 1.00 mol of oxygen molecules (O2). Participants explore the implications of oxygen being diatomic and how this affects the interpretation of the mole concept.

Discussion Character

  • Exploratory, Conceptual clarification, Homework-related

Main Points Raised

  • One participant expresses confusion about the relationship between moles and oxygen molecules, questioning if 1.00 mol of O2 means 2 oxygen molecules.
  • Another participant clarifies that a mole corresponds to Avogadro's number of molecules, suggesting that the diatomic nature of oxygen does not alter the count of molecules.
  • A third participant provides a calculation showing that 1 mol of O2 equals 6.0221415 × 10^23 molecules, emphasizing the definition of a mole.
  • One participant offers a comparison of moles to other quantifying units, explaining the scale of measurement.
  • Another participant notes that while there are two atoms in a diatomic oxygen molecule, O2 itself is considered one molecule.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the initial confusion regarding the relationship between moles and the number of oxygen molecules, but there is agreement on the definition of a mole and the nature of O2 as a molecule.

Contextual Notes

Some assumptions about the understanding of moles and molecular composition may be missing, and there is a lack of clarity on how participants define "molecule" versus "atom" in this context.

The questions is arranged like this:

1.00 mol of oxygen molecules ? oxygen molecules

I know an oxygen molecule is 02, so would it be 2 oxygen molecules?

It's my first day learning moles, so I'm very lost about the 1.00 mol.

A mole is equal to Avogadro's number in atoms/molecules. I don't think oxygen being diatomic plays a part in this since it's asking for the number of oxygen molecules.
 
1 mol of O2 x 6.0221415 × 10^23 molecules / mol = number of oxygen molecules in a mole
 
just think of "moles" as a quantifying unit

in order of magnitude: (small to big)
"one", "ten", "dozen", "hundred", "thousand", "million", "billion", "moles"

1 dozen of something = 1 x 12 = 12 something
1 moles of something = 1 x 6.022 x 10^23 = 6.022 x 10^23 something
 
There would be two oxygen atoms per a diatomic oxygen molecule, but O2 by itself is a molecule, not a single atom.
