The solute present in tank B will dissolve first.
What will be the answer to the given options?
The two tanks A and B contains the two solute in the form of the cube dissolved in a liquid.
Now tank A has the less number of solutes and the surface of the cube is large so the small amount will be exposed to the solution
Now in tank B, the cubes of the solute are higher in number and lower in size so more solutes are exposed to the liquid so the solute in tank B will dissolve faster.
Thus the solutes present in tank B will dissolve first.
