Question1

Part A

The barometer shown here (above) measures atmospheric pressure in millimeters of mercury (mmHg). According to this barometer, what is the atmospheric pressure P in inches of mercury (inHg)?

Express your answer in inches of mercury using four significant figures.

Part B

At a pressure of 945mbar , what would the height of the mercury in the column of a mercury barometer?

Express your answer numerically in millimeters of mercury.

Question 2

If one had a parking garage that was filled with cars such that each parking spot was occupied, it would make intuitive sense that if we had twice as many cars, the parking garage would need to be twice as big to maintain car density within the garage. But, is the same thing true if one is concerned with gas particles and not cars? The answer is Yes. More than a century ago Italian chemist Amadeo Avogadro postulated that V, the volume of a gas and n, the number of gas particles are directly proportional, when the temperature and pressure are held constant.

Part A

Avogadro's Law states that at a given temperature and pressure, what quantity is constant?

Explanation / Answer

Question 1

Part A:-   P=753.3mmHg=(753.3/25.4)inHg=29.65inHg

Part B:- P=945bar

                1bar=1mmHg

                therefore 945bar=945mmHg

Question 2

Part A:- V/n is const.

Part B:- V1/n1=V2/n2

              n2=0.15mole

Question 3

Part A:- V=KT

                V1/V2=T1/T2

                 V2=(T2/T1)*V1

                V
