Answer:
64 k
Explanation:
To figure this out you need to start with the ideal gas equation:
P
⋅
V
=
n
⋅
R
⋅
T
You have P (3.30 atm), V (3.5 l), n (2.20 moles) and you can look up the gas constant, R (0.082057 (latm)/(molK)).
We simply rearrange the ideal gas equation to get T by itself:
T
=
P
⋅
V
n
⋅
R
Then simply plug in the values you were given, making sure that the units are in liters, atmospheres, and moles (which they are, in this case):
T
=
3.30
atm
⋅
3.5
l
2.20
moles
⋅
0.082057
(l*atm)/(mol*K)
=
63.9799
K
Since volume was only given to 2 significant figures, we can only report 2 significant figures for our answer:
64 K.
