Question

Calculate the strength of 10 volume solution of hydrogen peroxide?

विकल्प

• 45.51 g L^-1

• 60.71 g L^-1

• 30.35 g L^-1

• 15.175 g L^-1

Answer 1

30.35 g L^-1 

Explanation:

\[\ce{2H2O2 -> 2H2O + O2}\]

⇒ 22.4 lit. of O₂ is produced from 68 gm of H₂O₂ 

10 litre of O₂ at STP is produced from = `(68 xx 10)/22.4` = 30.35 g L^-1
