A 0.4755g sample containing (NH4)2C2O4 and inert materials was dissolved in H2O and made strongly alkaline with KOH, which is converted NH4+ to NH3. The liberated NH3 was distilled into 50.00mL of 0.05035 M H2SO4. The excess H2S04 was back-titrated with 11.13 Ml of 0.1214 NaOH. Calculate the %N in the sample. Hint: Determine the moles of titrant consumed via using the prepared titrant and subtracting the equivalent moles used in back-titration.
