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

The correct answer is d. 4.7 atm

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
