Question

A gas occupies 4.31 liters at a pressure of 150 mm Hg. Determine the volume if the pressure is increased to 725 mm Hg.

Answer 1

Answer:

0.89 L

Explanation:

Applying,

Boyle's Law,

PV = P'V'..................... Equation 1

P represent initial pressure, V represent initial volume, P' represent final pressure, V' represent final volume

Make V' the subject of the equation

V' = PV/P'.............. Equation 2

From the question,

Given: P = 150 mm Hg, V = 4.31 liters, P' = 725 mm Hg

Substitute these values into equation 2

V' = (150×4.31)/725

V' = 0.89 L
