Question

19. 4.0 L of a gas at 1.0 atm is compressed into a 0.85 L cylinder. What is the pressure of the compressed gas if

its temperature remains constant?
a. 3.4 atm
c. 0.21 atm
b. 0.15 atm
d. 4.7 atm

Answer 1

The correct answer is d. 4.7 atm

Step-by-step explanation:

We apply Boyle Mariotte's law, where for a certain mass of gas at constant temperature, the pressure and temperature vary inversely proportionally: P1xV1 = P2xV2

P2= (P1xV1)/V2= (1,0 atm x 4,0 L)/0,85L= 4, 705882353 atm
