2. How many moles of nitrogen are in a 2145 mL sample of the gas at 1500. torr and 120 degree of Celsius?
3. Chlorine reacts with sulfite ion in the presence of water to give sulfate ion and chloride ion How many milliliters of Cl2 gas measured at 25 degree of Celsius and 734 torr are required to react with all the SO32- in 34.9 mL of 0.253 M Na2SO3 solution? The chemical equation is the following:
Cl2+SO32-+H2O --> 2Cl-+SO42-+H+
