Atank holds 10.3 mol of an ideal gas at an absolute pressure of 519 kpa while at a temperature of 361.38°c. (a) compute the container's volume (b) the gas is now heated to 651.6 °c. what is the pressure of the gas now?

(a) 62.57 L

(b) 801.94 kPa

Explanation:

Given:

= number of moles of gas = 10.3 mol

= initial pressure of the gas =

= initial temperature of the gas =

= final temperature of the gas =

= volume of the tank

R = universal gas constant =

Part (a):

Using Ideal gas equation, we have

Hence, the volume of the container is 62.567 L.

Part (b):

As the volume of the container remains constant.

Again using ideal gas equation,

Hence, the final pressure of the gas is now 801.94 kPa.
