Question

What is the volume of a 24.7 mol gas sample that has a pressure of .999 atm at 305 K?
A:619 mL
B:.691 L
C:619 L

Answer 1

Are you familiar with the ideal gass law?
PV = nRT

Answer 2

NO...

Answer 3

HELP :(

Answer 4

P = pressure (in atm)
V = Volume (in Liters)
n = number of moles
R = a constant (0.08206)
T = Temperature (K)

You can rewrite the equation to \[V=\frac{ nRT }{ P}\]
So \[V=\frac{ 24.7*0.08206*305 }{ 0.999 }\]

Answer 5

OH YEA I REMEMBER THAT :) LOL

Answer 6

I THINK ITS A IS THAT RIGHT?

Answer 7

?

Answer 8

if you calculate V, the answer will be in liters.
(24.7*0.08206*305)/0.999 = 618.8 LITER
So the answer would be C

Answer 9

OH TRUE I DIDNT DO THAT BUT THANK YOU SO MUCH :)
