Finding Volume Of 90.5 moles Ideal Gas
If
90.5 moles
of an ideal gas is at
1.77 atm
at
34.80 °C
,
what is the
volume
of the gas?
Applying the Ideal Gas Law, we first want to check if all units match
R 0.082057
L
atm
mol
-1
K
-1
We will have to convert our temperature value
34.80 °C
+ 273.15 =
307.95 K
Now, we're ready for
