Question

The volume strength of 1.5 N H2 O2 is a. 4.8 b. 8.4 c. 3.0 d. 8.0

Answer 1

Answer:

option b is correct

1.5 N means 1.5 g equivalent in 1 L solution

N=weight/eq.weight

So 1.5=wt/17 or wt=1.5*17=25.5g

From equation we know that 68 g of $H_{2} O_{2}$ gives 22.4 L of oxygen

so 25.5 g of $H_{2} O_{2}$ gives

=$\frac{22.4*25.5}{68}$

=8.4L
