Academics

1) A 12-liter tank contains helium gas pressurized to 160 .What size tank would be needed to contain this same amount of helium at atmospheric pressure (1 atm )?

2) An aerosol spray can with a volume of 250 ml contains 2.30 g of propane gas as a propellant.
a)If the can is at 22, what is the pressure in the can?

b)What volume would the propane occupy at STP?

c) The can says that exposure to temperatures above 130 degree F may cause the can to burst. What is the pressure in the can at this temperature?

3) Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. Suppose that the volume of a particular sample of gas is 8.40 L at 885 torr and 23 degree C.

a) How many grams of Cl2 are in the sample?

b) What volume will the Cl2 occupy at STP?

c) At what temperature will the volume be 15.20 L if the pressure is 877 torr?

d) At what pressure will the volume equal 6.50 L if the temperature is 54 degree Celsius?
