The Ideal-Gas Equation (Section)
Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. Suppose that the volume of a particular sample of Cl2 gas is 8.70 L at 895 torr and 24 °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 15.00 L if the pressure is 8.76 × 102 torr? (d) At what pressure will the volume equal 5.00 L if the temperature is 58 °C?
