When a sample which is having 0.5632 g of containing the NaNO2 and some inert material is allowed to react with the excess HSO3NH2, the volume of N2gas formed is calculated. Determine the mass percent of NaNO2 in the sample using the molar volume of N2 at 298.15K and100kPa. The volume of N2 gas corrected to 298.15K and 100kPa is calculated to be 112mL.
