Answer 1

Answer:

2)537.6 mL

Explanation:

Initial Meq.of H2SO4=30×1=30

Meq.of H2SO4 after passing NH3=30×0.2=6

∴ Meq.of H2SO4lost=30−6=24

Since, Meq. of  NH3 = Meq.of H2SO4lost=24

∴(w/17)×1000=24

or,    wNH3=0.408

∴  Volume of NH3 at STP = (22.4×0.408)/17

                                         =0.5376L=537.6mL
