AS chem unit 1 question
A 0.143g gaseous sample of ammonia occupied a volume of 2.86 x 10-4 m3 at a temperature T and a pressure of 100kPa
State the ideal gas equation, calculate the number of moles of ammonia present and deduce the value of the temperature T.
The gas constant R= 8.31
I have no idea if this is right or not but i did this...
pv=nRt so T= pv/nR
Volume- 0.000286
p-100,000
T-?
r-8.31
n-?
Ammonia =nh3( 14+3) =17
moles = mass/mr 0.143/17= 0.0084 mol
T=pv/nr 100,000 x 0.000286/ 0.0084 x 8.31 = 409 so T =409k???
If im wrong (which i probably am) how do i work it out?

So there's 0.143g of Ammonia right?
number of moles = what there is/Mr
0.143/17 = 0.00841...moles
T= PV/NR
T= (100000 x 0.000286)/(8.31 x 0.00841...) = 409K
Yessiree. You are correct.
number of moles = what there is/Mr
0.143/17 = 0.00841...moles
T= PV/NR
T= (100000 x 0.000286)/(8.31 x 0.00841...) = 409K

Aeon, you're aware you've neg repped me right with a message saying 'Thanks'?
LOL ! sorry i thought I gave you positive rep , can i change it?
Your rep wouldn't be worth anything anyway, so it shouldn't matter.
He's right. Chillax... just be more careful next time and give me positive rep when your own rep is high...
Esma
Oh sugar!I tried to give back Hippy snake a +ve rep because he got negged by mistake but I cliked on ToiletPaper8 by mistake!!Sorryy..(My rep is probably worth nothing too)..Sorry though
your's is worth something

Ahh, a tricky dilemma indeed
. I'll rep Hippysnake tomorrow. No one needs to owe anyone rep. Problem solved, and I'm sure my rep is worth more anyway 
Hahahaha.....why me!? WHY!?
EDIT: At the post above. Fanx luv.

Haha, yea
I found it rather amusing how you proclaimed to have 4,000 posts when you had 3,999 and now you have 4,001
Did you ever make your 4,000th post?

You need 150 posts, you already have the reputation required
