Agas that exerts a pressure of 125.0 mm hg in a container with a volume of ml will exert a pressure of 145 mm hg when transferred to a container with a volume of 0.4650 l.

Initial volume of container = 0.5394 L (≅0.539 L)

Explanation:

Given:

Initial pressure of gas, P1 = 125.0 mmHg

Final pressure of gas, P2 = 145 mmHg

Final volume, V2 = 0.4650 L

To determine:

The initial volume V1 occupied by the gas

Explanation:

Based on the ideal gas equation

where P = pressure, V = volume ; n = moles of gas

R = gas constant, T = temperature

At constant n and T, the above equation becomes:

PV = constant

This is the Boyle's law
