What is the net volume of nitrogen collected? 378.5-20.4-358.1 3. What is the partial pressure of the nitrogen? 756.2-16.5739.7 4. What was the volume of N, corrected to STP conditions?

Answer 1

Page Solution:- The dreaction occan is NaNO₂ (aq) + HSO, NH, cap - NaH sou (aq) +H₂0 (4) tN₂(g) S I mol of Na No₂ produce Imol of N₂ The no. nog moles Na No used g molarity x volume inks o fom х 2015 mL loro limbinary loro lant 01612 moles. Hence, the Na produced that should produced must be og 0.01612 meles. 7 Percentage error can be calculated as / Error = Theoretical value Experimendol welee 1x rool Theoretical volume Theoutical value is the value we have calculated in question
