Which statement is true for solution of 0.020 M `H_(2)SO_(4)` ?

Options

A. 2 litre of the solution contains 0.020 mole of `SO_(4)^(2-)`
B. 2 litre of the solution contains 0.080 mole of `H_(3)O^(+)`
C. 1 litre of the solution contains 0.020 mole `H_(3)O^(+)`
D. None of these

Answer

B

Explanation

`[H_(3)O^(+)]=2xx0.02=0.04M`
`therefore2` litre solution contains 0.08 mole of `H_(3)O^(+)`.
