Question

The volume (in L) that would be occupied by 5.00 mol of O2 at STP is
A. 0.411 L.
B. 22.4 L.
C. 41.6 L.
D. 112 L.

Answer 1

I am not a Chemist, but I took Chemistry and passed :-D.

\[P\times V=n\times R \times T\]
Substitute the given values.
P is pressure
V is volume
n is the number of moles of molecules
T is the absolute temperature
R is the gas constant (.0821)

I maybe right or wrong about .0821 being the gas constant...

Answer 2

There is also another way to solve this ^_^.
1 mole occupies 22.4 L at STP.
\[5.00 \times 22.4 = 112L\]
Please note:
\[5.00~moles \times 22.4 L/mole = 112\]

Answer 3

thank you :)

Answer 4

Do you understand what I was trying to say? Chemistry is sometimes confusing :-P, so I just want to check.

Answer 5

yes I do
