A helium-filled weather balloon has a volume of 603 L at 16.9°C and 755 mmHg. It is released and rises to an altitude of 4.05 km, where the pressure is 534mmHg and the temperature is –7.1°C. The volume of the balloon at this altitude is ____ L.
a 2.802g sample of an unknown pure metal (M) is added to a 0.2 L solution of 2 mol/L H2SO4(aq). The metal reacts with the acid until the metal is completely gone to form M3+(aq) ion in the solution and produces hydrogen gas that is collected. The hydrogen gas that is collected over water that is isolated from the reaction has a volume of 0.82 L at 25 degrees Celsius and a total pressure of 704.0 mmHg. How many moles of H2(g) are produced? Write a balanced equation for the reaction of M with H2SO4(aq). What is the identity of metal M?

Two students perfomed an experiment on the decomposition of hydrogen peroxide. One student was in Wisconsin where the atmospheric pressure was 0.996 atm. The other was in Colorado, where the atmospheric pressure was 0.832 atm. Both reactions were performed at the same temperature and produced the same number of moles of oxygen gas. How do the volumes of gases collected compare? Are they the same or not? Explain.
