Homework Statement
A Sample of gas 250 mL at 37 C and 730 torr . What volume would gas occupy at standard conditions ?
Homework Equations
pv = nRT
V2 = T2P1V1
-------
T1P2
The Attempt at a Solution
Sample Gas
V = 250 mL ( 0.250 L )
P = 730 torr ( .960 atm )
T = 310 K
Standard Condition
T = 273
V = 22.4 L
P = 1 atm
I'm confused because sample gas formula is already given and then find the gas under stand condition ?
Do I just use standard condition formula and drop the other ones ?
If I use pv = nRT then I get following
v = (0.250 L / 22.4 L = .0111 mol) since STP 1 mol = 22.4 L
p = .960 atm
R = 0.08260 ( constant gas )
T = 310 K
v = (.0111 mol ) (0.08260)(310)
--------------------------
.960 atm
Answer = .290 L
The answer doesn't seem to make sense. Any correction ?
