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

THE PRESSURE EXERTED BY THE GAS IS THEREFORE 2.88 atm.

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

the answer to this question is 3.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
