# Helppss watch

1. A flask, capacity 600cm3, was used to calculate the molar volume of sulphur dioxide.

The following data was obtained.

Mass of evacuated flask = 512.97g

Mass of flask+ sulphur dioxide = 514.57g

Calculate the molar volume of sulphur dioxide �F߁(
2. How many moles (n) of SO2 do you have?
Molar vol =600/n

Note that this is molar volume at the (unstated) temperature and pressure. This varies when T or P change.
3. 1 mole of sulfur Dioxide
4. 1 mole of sulfur dioxide
5. (Original post by ayeeyaboiii)
1 mole of sulfur dioxide
wait i 1.6/64.1 = 0.25 moles
6. (Original post by ayeeyaboiii)
wait i 1.6/64.1 = 0.25 moles
That doesn't seem right...
Want to recheck it?
7. i'm lost, do i find the gfm and then find the find the difference between the flask with sulfur and evacuated ?

At the moment you just wanr to do 1.6/64 correctly 😁 as you nees the number of moles.
Then proceed as my first reply suggests.

is it 0.025
10. (Original post by ayeeyaboiii)
is it 0.025
Great.

Now, molar volume (cm3) = vol/n
= 600/0.025
11. (Original post by TutorsChemistry)
Great.

Now, molar volume (cm3) = vol/n
= 600/0.025
24,000
12. Spot on.

Remember this value. It is the molar volume in cm3 of any gas at 298K and 1 atmosphere pressure.
13. so is that Molar Volume of sulfur dioxide ?
14. Yes.
15. (Original post by TutorsChemistry)
Yes.
thank you so much who every you are
