I missed an entire week of class, and I have absolutely no idea how to do these questions. If anybody could set up the question or explain how to do the problems, it would be really appreciated. I'd also really appreciate it if people refrained from saying "Do your own homework," considering that I would if I knew how to do so. Thank you again.
1.
Exactly 10.0 L of O2 at 25oC is heated to 100.0oC. What is the new volume if
the pressure is kept constant?
2.
The gaseous contents of an “empty” aerosol spray can are at a pressure of 110.0 kPa at room temperature (20.0C). What pressure is generated inside the can if it is thrown into a fire where the temperature is 750.0C?
3.
A large balloon containing 400.0L of hydrogen gas is released from earth at 21.0 oC and 101.3kPa. What volume will the gas occupy at -67 oC and 22.0 kPa in the upper atmosphere?
4.
A sample of O2 with an initial temperature of 50.0C and a volume of 105 L
is cooled to 25C. The new pressure is 105.4 kPa and the new volume is
55.0 L. What was the initial pressure of the sample?
5.
How many molecules of gas will an 845 cm3 container hold at -20.0C and a pressure of 106 kPa?
6.
A 35.0-L tank contains 7.00 mol of compressed air. If the pressure inside the
tank is 500.0 kPa, what is the temperature of the compressed gas?
7. What would be the density of CO2(g) collected at 27.0C and 104.5 kPa?
HINT: Assume any volume of CO2(g)
8. A gas with a mass of 0.975g was measured to be 500.0mL at 27.0 oC and 152.0kPa.
Calculate the molar mass of the gas.
