Problem with Moles
« on: October 13, 2024, 11:15:53 PM »
How many atoms are in 2.5 moles of oxygen gas?

I got 1.5 * 10^24 as my answer, but the answer key got 3.0 * 10^24.

Also, I thought that oxygen gas took molecules? Is this because oxygen is diatomic?

Thank you!

Yes, oxygen is diatomic - so what you calculated is number of molecules, not number of atoms.

One mole of oxygen means "one mole of O2".
