a liquid compund was vaporized at 100 degrees C and 755 mmHg to give 185 mL of vapor. Th vapor weighed 0.427 grams. What is the molecular weight of the compound?

(a) What is the pressure in psi (pounds per square inch) on the given pressure gauge used for scuba diving? (b) How many pascals (Pa) does this correspond to?

At 570 mm Hg and 25.0 celcius a gas sample has a volume of 2270 ML. What is the final pressure  (in mm Hg) at a volume of 1250 and a temp of 280 celsius?

The non-ideal molar volume of gaseous helium is approximately 20. L/mol. What is the density of this gas, in g/L?

A helium filled weather balloon has a volume of 502L at 14.9 degrees Celsius and 751mmHg. It is released and rises to an altitude of 2.88km, where the pressure is 595mmHg and the temperature is -2.1 degrees Celsius. What is the volume of the balloon in liters?

A colleague of yours takes a bunch of pressure readings while you are gone. You return to realize that he has invented a new unit: his body mass of 180lb per 1mile?. He calls this unit Bob per Bob's Block. 1mile = 63360 inches. What is the pressure of 9 Bobs per Bob's block in a real unit of pressure, pounds per square inch (PSI)? Use just one sig fig in your answer: x10^ PSI

6. The ideal gas law is a very simple mathematical relationship that relates several physical properties of a gas. This law is only valid when the behavior of a gas is idealized according to three principal assumptions. (i) State the three assumptions made about an ideal gas, and for each assumption (ii) explain which physical property of a gas would be affected if that assumption was not made.
