How many molecules of oxygen are in 3.4 mole oxygen?



Answer:
Just multiply by the Avogadro's Number.

3.4 moles Oxygen x 6.023 x 10^23 molecules/ one mole Oxygen

The moles cancel and you are left with molecules. = 2.047x10^24
32 grams of O2 are in 1 mole of O2
3.4?

I think that's a trick question.
2.05*10^24

You have 3.4 moles of O2. There are 6.022*10^23 molecules of oxygen in 1 mole of oxygen. Multiply avogadro's number by 3.4 and you have your answer.
all you have to do here is multiply your number of moles by avogradro's number (6.02x10^23)

when done you will end up with: 2.0x10^24 including only two significant figures
