Calculate the volume strength of 1.5 n h2 o2 is a. 4.8 b. 8.4 c. 3.0 d. 8.0

1.5 N = 1.5 g eqwt in 1 L solution.

N= weight/eq.wt (eq wt for hydrogen peroxide = 17 g)

Therefore, 1.5 = wt/17 or wt = 1.5 X17 = 25.5 g

Now, from equation we know that 68 g of H2O2 gives 22.4 L of Oxygen.

Therefore, 25.5 g of Hydrogen peroxide gives-

22.4 X25.5/68

= 8.4 L

So the answer will be ‘b’
