Firstly molarity is converted into normality as Molarity

\times

mol. wt. = Normality

\times

Eq. wt.
For

H_{2} S O_{4}

1 \times 98 = N \times 49

N = \frac{98}{49} = 2

For

N a O H,

1 M = 1 N

Now from normality equation

H_{2} S O_{4} = N a O H

N_{1} V_{1} = N_{2} V_{2}

2 \times V_{1} = 1 \times 20

V_{1} = \frac{20}{2} = 10 m L

of

H_{2} S O_{4}
