# If 4.0 moles of a gas at a pressure of 5.4 atmospheres have a volume of 120 liters, what is the temperature?

Dec 7, 2016

1973 k

#### Explanation:

Idle gas equation is

PV = nRT
P = 5.4
V = 120
r = 0.08206
T = ?

$5.4 \cdot 120 = 4 \cdot 0.08206 \cdot T$
$648 = 0.3284 \cdot T$
$648 = 0.3284 T$
so
$T = \frac{648}{0.3284} = 1973$

Hence answer is temperature is 1973 k
