Match the following :

	List-I		List-II
A)	50vol of H2O2	I)	300 g/L of H2O
B)	1 vol of H2O2	II)	44.8 vol of H2O2
C)	30% (w/V) of H2O2	III)	22.4 vol of H2O2
D)	4 molar H2O2	IV)	4.46 molar of H2O2
		V)	0.303 g/100 ml of

	(A)	(B)	(C)	(D)
1)	IV	V	III	II
2)	V	IV	III	II
3)	I	V	III	II
4)	IV	V	I	II

(A) 10 vol. strength = 0.893M = 1.786N = 3.03% (w/v)
      10 vol. strength$\Rightarrow$ 3.03% (w/v)
      50 vol. strength $\Rightarrow$ ??4.46  molar of H₂O₂

(B)  1 volume strength of H₂O₂
       10 vol = 3.03% (w/v)
       1 vol = ?? 0.303 g/100 ml of  H₂O₂

(C) 30%(w/v) of H₂O₂ means

  30 gm of H₂O₂ present in 100ml of  H₂O₂ solution (0.1lit)

???  -------------------present in 1000ml of  H₂O₂ solution (1lit)

i.e.. 300gr/liter

(D)  4 MOlar H₂O₂ solution
      10vol ----- 0.893M
      ?? vol ----- 4M

44.79 vol of H₂O₂.
