Question

Calculate the equivalent mass of ()2 .

Answer 1

Answer

Correct option

D

49u

The molecular formula of sulfuric acid is H

2

SO

4

.

Its molecular mass is =(1×3)+32+(16×4)=2+32+64=98u

The expression for the equivalent weight of an acid is as given below.

Equivalent weight =

Number of replaceable H

Molecular mass

sulfuric acid contains two replaceable hydrogen.

Substitute values in the above expression.

Equivalent weight =

2

98

=49u
