Question

Answer 1

$3 N$ means $3$ g eqwt. in $1$ L solution.

$N = \frac{weight}{eq. wt.}$ .

$($ eq. wt. for hydrogen peroxide $= 17$ g $)$

Therefore, $3 = \frac{wt}{1 7}$ or $wt = 3 \times 17 = 51$ g.

Now, from the equation, we know that $68$ g of $H_{2} O_{2}$ gives $22.4$ L of Oxygen.

Therefore, $51$ g of hydrogen peroxide gives $22.4 \times \frac{5 1}{6 8} = 16.8$ L.

Thus, volume strength is $16.8$ L, because volume strength is the volume of oxygen at STP given by one volume sample of hydrogen peroxide on heating.

Answer 2

3 N

means

3

g eqwt. in

1

L solution.

N = \frac{weight}{eq. wt.}

.

(

eq. wt. for hydrogen peroxide

= 17

g

)

Therefore,

3 = \frac{wt}{1 7}

or

wt = 3 \times 17 = 51

g.

Now, from the equation, we know that

68

g of

H_{2} O_{2}

gives

22.4

L of Oxygen.

Therefore,

51

g of hydrogen peroxide gives

22.4 \times \frac{5 1}{6 8} = 16.8

L.

Thus, volume strength is

16.8

L, because volume strength is the volume of oxygen at STP given by one volume sample of hydrogen peroxide on heating.
