a. Given the following set of values for a gas, calculate the unknown quantity: P = 743.3 mm Hg V = ? L n = = 0.1021 mol T = 23.3 °C V = L b. Given the following set of values for a gas, calculate the unknown quantity: P = ? atm V = 28.4 mL n = 0.007052 mol T = 20.5 °C P = c. Given the following set of values for a gas, calculate the unknown quantity: P= 1.079 atm T = atm V = 44.7 mL n = 0.003411 mol T = ? K K

A 10.0 L sample of carbon dioxide gas has a temperature of 500.0 K. If the volume of the gas is decreased to 2.2 L at constant pressure, what is the final temperature of the gas? 2300 K 110 K 0.044 K 23 K

When the valve between the two containers is opened and the gases are allowed to mix, how does the volume occupied by the N2N2 gas change? How does the volume of the O2 gas change when the gases mix?

For many purposes we can treat methane (CH,) as an ideal gas at temperatures above its boiling point of –161. °C. Suppose the temperature of a sample of methane gas is raised from 50.0 °C to 98.0 °C, and at the same time the pressure is decreased by 10.0%. O increase x10 Does the volume of the sample increase, decrease, or stay the same? O decrease O stays the same If you said the volume increases or decreases, calculate the percentage change in the volume. Round your answer to the nearest percent. |%

1. A sample of gas at 0.5 atmospheres is compressed until it is under 2.5 atmospheres. The temperature is measured as 900 K after it is compressed. What was the temperature of the gas before its pressure changed? Round to the nearest hundredth. O 150 K 50 K O 450 K 180 K

A sample of gas is contained in a tube under a mercury plug. V = heat ↑ B A C A B The gas sample has a volume of 28.2 µL at 20.0 °C.
