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
Correct Answer: B
Solution :
\[[{{H}_{3}}{{O}^{+}}]=2\times 0.02=0.04M\] \ 2 litre solution contains 0.08 mole of \[{{H}_{3}}{{O}^{+}}\].
