Which statement is true for solution of 0.20 M H_(2)SO_(4)

Answer»

2 litre of the solution contains 0.020 mole of `SO_(4)^(2-)`
2 litre of the solution contains 0.080 mole of `H_(3)O^(+)`
1 litre of the solution contains 0.020 mole `H_(3)O^(+)`
NONE of these

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