300 mL
Solution:- (B)
300
m
L
Let
V
be the volume of
H
2
S
O
4
required.
Given:-
M
H
2
S
O

=
0.1
M
M
N
a
O
H
=

M
V
N
a
O
H
=
30
m
L
Now, as we know that
N
1
V
1
=
N
2
V

∵
N
=
n
×
M
Whereas
n
is the valence factor
Therefore,
n

=
n

For
H

S
O

;
n
=

For
N

O
H
;
n

30
⇒
V
=

0.2
⇒
V
=
300
m
L
Hence
300
m

is required to neutralize
30
m
