\( \mathrm{P} \)
Once Tom and Jerry entered into a chemistry lab in which a chemist was preparing a solution of \( \mathrm{H}_{2} \mathrm{SO}_{4} \) in a two litre container. He labelled the solution as 'density \( =5.96 \mathrm{~g} / \mathrm{ml}, 5 \mathrm{~m} \) ' which occupied half of the volume of the container. Tom W saw the solution and a mischief came in his mind. As the chemist left the lab, Tom tried to throw the solution on Jerry. In doing so, some of the solution fell on the floor. Tom added water in the container to fill it up to the original level. The chemist returned back and got astonished to see the result of analysis that showed 'density \( =0.4 \mathrm{~g} / \mathrm{ml} \) and \( \% \mathrm{w} / \mathrm{w}=49 \) '.
What was the molarity of \( \mathrm{H}_{2} \mathrm{SO}_{4} \) solution present initially in the container?
(a) \( 5 \mathrm{M} \)
(b) \( 1.92 \mathrm{M} \)
(c) \( 20 \mathrm{M} \)
(d) \( 10 \mathrm{M} \)
