The reaction between 0.0985g of NaNO2 and excess HSO3NH2 occurs in an Erlenmeyer flask submerged in a water bath at 21.83 degrees celsius. The volume of the system is 268 mL, the volume occupied by the reagents and other equipment is 69 mL. Determine the volume occupied by the gas. The initial pressure was 98.76kPa. The highest pressure obtained was 115.65 kPa. Calculate the molar volume of N2 at the reference conditions of 298.15 kPa. (you may not use PV=nRT)
