Question

A chemist compresses a 1.8 L sample of carbon dioxide gas at 2.4 atm to a final volume of 1.5 L. Assuming the temperature is constant,what is the final pressure,in arm,exerted by the gas

Answer 1

THE PRESSURE EXERTED BY THE GAS IS THEREFORE 2.88 atm.

Step-by-step explanation:

Boyle's law states that at constant temperature, the volume of a given mass of gas is inversely proportional to the pressure of the gas.

Mathematically, P1 V1 = P2 V2

Write out the values of the variables given:

P1 = 2.4 atm

V1 = 1.8 L

V2 = 1.5 L

P2 = unknown

Re-arranging the variables by making P2 the subject of the equation, we have:

P2 = P1 V1 / V2

P2 = 2.4 * 1.8 / 1.5

P2 = 2.9=88 atm

Hence, the pressure exerted by the gas is therefore 2.88 atm
