# a. If the pressure on a 1 25-mL sample of gas is increased from 755 mm Hg to 899 mm Hg at constant temperature, what will the volume of the sample become? If a sample of gas is compressed from an initial volume of 455 mL at 755 mm Hg to a final volume of 327 mL at constant temperature, what will be the new pressure in the gas sample?

Interpretation Introduction

(a)

Interpretation:

The final volume of the given sample is to be calculated.

Concept Introduction:

Boyle’s law states that if the temperature and the moles of gas remain constant, then the pressure exerted by the gas is inversely proportional to the volume occupied by the gas in that space. The expression for the same is,

P(pressure)1V(volume) or PV=k(constant).

Explanation

The given initial volume, V1 of the sample of a gas is 125mL.

The given initial pressure P1 of the sample of a gas is 755mmHg.

The given final pressure P2 of the sample of a gas is 899mmHg.

If the sample of gas possesses two different conditions then, the expression for the Boyle’s law is,

P1V1=P2V2

Where,

P1

• is the initial pressure of the gas.
• P2 is the final pressure of the gas
• Interpretation Introduction

Boyle’s law states that if the temperature and the moles of gas remain constant, then the pressure exerted by the gas is inversely proportional to the volume occupied by the gas in that space. The expression for the same is,
