Consider following vessel of given dimensions Cubical vessel is filled completely with $2 M H_{2} SO_{4}$ solution, whereas spherical & cylindrical vessels are empty (Take $π = 3$ ) (Atomic mass of $Br = 80$ )

Which acid will be left in cylindrical container and its molarity will be

Options:

Answer:

Solution:

Volume of Cube: $V_{c u b e} = 10 \times 10 \times 10 = 1000 c m^{3}$ .

Volume of Sphere: $V_{s p h ere} = \frac{4}{3} \times 3 \times 5^{3} = 500 c m^{3}$ (taking $π = 3$ ).

Volume transferred to Cylinder: $V_{re m} = 1000 - 500 = 500 c m^{3}$ , containing $m o l es = 2 M \times 0.5 L = 1 m o l e$ .

Molarity in Cylinder: Calculated using the total cylinder volume ( $V_{cy l} = 3 \times 5^{2} \times 10 = 750 c m^{3} = 0.75 L$ ), giving $M o l a r i t y = \frac{1}{0.75} = \frac{4}{3} M$ (Option D)
