1. The pressure of 5.85 L of an ideal gas in a flexiblecontainer is decreased to one-third of its original pressure, andits absolute temperature is decreased by one-half. What is thefinal volume of the gas?
2. A piece of sodium metal reactscompletely with water as follows:
2Na(s) + 2H2O(l) → 2NaOH(aq) +H2(g)
The hydrogen gas generated is collected over water at27.0°C. The volume of the gas is 175 mL measured at0.969 atm. Calculate the number of grams of sodium used in thereaction. (The vapor pressure of water at 27.0°C =0.0352 atm.)
