Answer:
The temperature inside the tank will be 170,73 K (-99.27 °C)
Let's see how do you solve this with the Ideal gas law
Explanation:
PV = nR T
where P is pressure
where V is volume
where n are the moles
where R is the constant gas
where T is temperature in K°
3.50 atm . 20,0 L = 5 moles x 0.082 l atm / mol . K
70 L. atm = 0,41 L.atm/K . K
70 L. atm / 0,41 K/L.atm = K
170,73 K
T° in K - 273K = T° C
