Mathew · Answer 1

The correct answer is C) 0.64kPa

Boo Bug · Answer 2

Answer: Option C) 0.64kPa

Explanation:

Given that,

Original volume V1 = 11.2 L

original pressure P1 = 0.860kPa

New volume V2 = 15.0 L

New pressure P2 = ?

Since pressure and volume are involved while temperature is constant, apply Boyle's law

P1V1 = P2V2

0.860 kPa x 11.2 L = P2 x 15.0L

9.632 kPaL = P2 x 15.0L

P2 = 9.632 kPaL / 15.0L

P2 = 0.64 kPa

Thus, the pressure of the gas is 0.64kPa
