Answer 1

Answer:

correct answer is 1.8 can't show u the working , sorry

Answer 2

Given: 2 L of gas A at 1.5 atm and 3 L of gas B at 2 atm are mixed in a 5 L container

To find: The final pressure in atm

Explanation: Since the temperature and gas constant is equal for all the gases in this question, therefore it can be neglected in the equation.

In this question, the equation used will be:

P1V1+ P2V2 = P3V3

where P1= 1.5 atm, P2= 2 atm, V1= 2 L , V2= 3 L

V3= 5 L

Putting values in equation:

=> 1.5*2 + 3*2= 5P3

=> 3 +6 = 5 P3

=> 9 = 5 P3

=> P3 = 9/5

= 1.8 atm

Therefore, the final pressure in atm will be 1.8 atm.
