Document Summary

Container a holds 762 ml of an ideal gas a at 2. 30 atm. Container b holds 179 ml ideal gas b at 4. 40 atm. At 1 atm and 0 oc, a 5. 04 l mixture of methane (ch4) and propane (c3h8) was burned producing 20. 9 g of co2. Total moles before 0. 225 mol moles co2 after 0. 457 mol, mol fraction ch4 0. 444, mole c3h8 0. 556. A 0. 564 gram sample of a metal (m) reacts completely with sulfuric acid according to the reaction below. A volume of 219 ml of hydrogen is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 756. 0 torr and the temperature is 25oc. The vapor pressure of water at 25oc is 23. 8 torr. Note: all the book questions for this chapter are great. For extra practice for the gas law problems just do a lot of the book homework problems.
