2. How many moles of nitrogen are in a 2145 mL sample of the gas at 1500. torr and 120 °C? 3. Chlorine reacts with sulfite ion in the presence of water to give sulfate ion and chloride ion How many milliliters of CI, gas measured at 25 °C and 734 torr are required to react with all the S0,2 in 34.9 mL of 0.253 M Na, SO, solution? The chemical equation is the following: Cl2+ SO2+ H,O 2Cl +SO2+H* 4 3 Carbon dioxide can be generated by the reaction of hydrochloric acid with calcium carbonate. How many milliliters of dry CO, at 20.0 °C and 755 torr can be prepared from a mixture of 32.1 g of CaCO, and 203 mL of 0.245 M HCI?

Question

I need help with these three questions, they are all interconnected so I grouped them as one. 

2. How many moles of nitrogen are in a 2145 mL sample of the gas at 1500. torr and 120 °C?
