1. 1/4 mole of 02 gas and 0.15 mol of hydrogen gas are mixed in a liter container at a temperature of 25°C. What is the total pressure of the gaseous mixture? 2. A sample of gas was collected over H20 at 27°C and 600 torr barometric pressure; volume 260 mL. (The vapor pressure of water at 27°C = 25 torr). What volume would the dry gas %3D occupy at STP? 3. A gas in a 1.00 L container is allowed to expand to a volume of 5.00 liters. If the initial pressure is 748 torr, what is the final pressure if the temperature does not change? 4. A balloon containing 1.00 liter of e at STP is purchased in an air- conditioned store, in which the temperature is 25°C, and caried outside where it heats to 45°C. if there is no pressure change, what is the final volume?

Please take note of the direction.
Transcribed Image Text:1. 1/4 mole of 02 gas and 0.15 mol of
hydrogen gas are mixed in a liter
container at a temperature of 25°C.
What is the total pressure of the
gaseous mixture?
2. A sample of gas was collected over
H2O at 27°C and 600 torr barometric
pressure; volume 260 mL. (The vapor
pressure of water at 27°C = 25 torr).
What volume would the dry gas
occupy at STP?
3. A gas in a 1.00 L container is allowed
to expand to a volume of 5.00 liters. If
the initial pressure is 748 torr, what is
the final pressure if the temperature
does not change?
4. A balloon containing 1.00 liter of e at
STP is purchased in an air-
conditioned store, in which the
temperature is 25°C, and carried
outside where it heats to 45°C. if
there is no pressure change, what is
the final volume?
