Worksheet for Chapter 11 Gases and Gas Laws CHE 120 The barometer in your lab only reports in inches. if your reading is 30.5 in Hg, what is the atmospheric pressure in 1) (a) mm Hg (b) atm Match the correct unit with the following gas attributes- Volume 2) 1) kPa- 2) °C 3) mL. - 4) K 5) mm Hg- 6) atmospheres (atm)- 7) L- Denver, Colorado is about 1.6 kilometers (1 mile) above sea level. The atmospheric pressure of Denver drops to 12 pounds per square inch (psi) at this altitude. What is the pressure in: 3) (a) atm. (b) inches (c) mm Hg A scuba tank contains a mixture of He and O2 gases at 7.00 atm. If the pressure of 0 gas is 1140 mmHg, what is the partial pressure of He gas in the tank? 4) For a cylinder containing helium gas, indicate which cylinder, A or B, represents the new volume for the following changes (n and Tare constant): 5)

Explanation / Answer

Ans 1 :

a) 1 in Hg = 25.4 mmHg

So 30.5 in Hg = 30.5 x 25.4 mmHg

= 774.7 mmHg

b) 1 in Hg = 0.0334211 atm

So 30.5 in Hg = 30.5 x 0.0334211 atm

= 1.019 atm
