Final answer:
To find the new pressure in the tank, use the combined gas law equation and plug in the given values for initial pressure, initial temperature, final temperature, and the percentage of gas withdrawn.
Step-by-step explanation:
To find the new pressure in the tank, we can use the combined gas law equation:
P1V1/T1 = P2V2/T2
Given that the initial pressure (P1) is 9 atm, the initial temperature (T1) is 16°C (which converts to 289.15 K), and 65% of the gas is withdrawn, we can calculate the new pressure (P2) using the final temperature (T2) of 60°C (which converts to 333.15 K) and the initial volume (V1) which remains constant.
Plugging in the values:
(9 atm)(V1)/(289.15 K) = P2(V1)/(333.15 K)
Now, solve for P2 to find the new pressure in the tank.
