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(

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.

1 mole of sulfur Dioxide
1 mole of sulfur dioxide

1 mole of sulfur dioxide
wait i 1.6/64.1 = 0.25 moles
Original post by ayeeyaboiii
wait i 1.6/64.1 = 0.25 moles
That doesn't seem right...
Want to recheck it?
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

is it 0.025
Great.
Now, molar volume (cm3) = vol/n
= 600/0.025

Great.
Now, molar volume (cm3) = vol/n
= 600/0.025
Now, molar volume (cm3) = vol/n
= 600/0.025
24,000
Spot on.
Remember this value. It is the molar volume in cm3 of any gas at 298K and 1 atmosphere pressure.

so is that Molar Volume of sulfur dioxide ?

Yes.
