During the discharge of a lead storage battery,the density of sulphuric acid fell from 1.294 g/mL (39% H2SOby weight) to 1.139 g/ML (20% H2SOby weight).The battery holds 3.5 L of the acid and the volume remains practically constant during discharge.
Q.
Total H2SO4 used is   
  • a)

  • b)
    5.15 mol
  • c)
    2.32 mol
  • d)
    2.82 mol
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Comprehension TypeThis section contains a passage describing theory, e...


Thus, H2SO4 consumed per litre = (505 - 228) g = 277 g
Total acid in 3.5 L = 969.5 g
H2SO4 consumed = 9.89 mol
Electrons consumed = 2 mol for 2 mol H2SO4 
= 1 mol for 1 mol H2SO4
