Answer:
T

447
K
≈
174
∘
C
.
Step-by-step explanation:
This is what we're given:
P
(pressure), which is
1.95 atm
.
V
(volume), which is
12.30 L
.
n
(number of moles), which is
0.654
moles of neon gas.
We have to find
T
, or temperature. To do this, we'll need to use the Ideal Gas Law, which is:
P
V
=
n
R
T
Rearranging this equation to get temperature on one side, we get:
T
=
P
V
n
R
Pressure is in
a
t
m
and volume is in
L
. This tells us that we'll need to use the value of
0.08206 L atm/K mol
for
R
, the ideal gas constant.
Plugging in all of the values, we can solve for temperature:
T
=
p
V
n
R
T

We can then convert to celsius, which equals to around
