## rebeccaskell94 2 years ago One mole of N2 gas at STP will occupy what volume? 44.8 L 22.4 L 44.2 L 88.4 L none of the above How in the world do I figure this out?

1. panlac01

textbook

2. ash2326

one mole of any gas will occupy 22.4 liters

3. ash2326

at STP

If I could find it in my textbook I would have. OS is my last resort. I don't expect people to do my homework @panlac01

I am still looking for a textbook for quick and dirty tips on chemistry to upload on my website. I think not until this fall when I get an access to mastering courses

lol

@rebeccaskell94 Please check this, you'll understand how it's 22.4 liters http://hyperphysics.phy-astr.gsu.edu/hbase/kinetic/idegas.html

whoa o.o

10. panlac01

ay yai yai

So If it is one molecule at N2 do I just multiply but 2 or?

12. goformit100

|dw:1343414493927:dw|

I don't think that is right. 28 is not an option

14. goformit100

sorry @rebeccaskell94 i went wrong at first attempt, following is the correct answer...

@karatechopper are you good at this?

17. karatechopper

Beccs i am only starting bio :) far from chem

darn lol anyone else you know that is good?

19. hba

easy one and u dont know how to do it

I need help not patronization. Thanks

21. hba

22. hba

do u know the mole formula

no

I haven't been studying chemistry for long

25. hba

Moles = Volume( in dm3) / 24

26. goformit100

then i was 100% correct

27. hba

no but damn it it is an ideal case

28. hba

"1 mole of an ideal gas at STP has volume = 22.4 L"

oh

30. hba

^^ thats ur answer

31. hba

u wanna know how u get it

32. hba

PV = nRT;at STP:T = 273K , P = 1 atm V/n = RT/P = (0.08206 Latm/moleK) x (273K) / (1 atm) = 22.4 L/mole

33. hba

thats it i guess

so...much. @ . @

35. goformit100

at ideal state P= 1atm v= we have to find n=1mole (given) R=0.0821 litre-atm-mol^-1 k^-1 t=273.37 K
