In an experiment of establish relationship between loss in weight of an immersed soild with the weight of water displaced by it, the correct set-up shown in Fig.

Four students A, B, C and D while performing an experiment on establishing the relation between the loss of weight of a small solid when fully immersed In tap water and the weight of water displaced by it, used four different shapes of overflow-cans containing water The arrangement, the would give correct results, is that of student:

Establish the relationship between molecular weight and vapour density with the help of avogadro's hypothesis.

For a steel boat floating on a lake, the weight of the water displaced by the boat is

Give the relationship between the equivalent weight and molecular weight of KMnO_4 in acidic medium.

Give the relationship between the equivalent weight and molecular weight of KMnO_4 in alkaline medium.

Give the relationship between the equivalent weight and molecular weight of KMnO_4 in neutral medium.
