Question

. State the relation between the
density of a body and that of a
liquid in which the body:
(a) sinks.
(b) floats completely submerged.​

Answer 1

Explanation:

The problem gives you all the information you need in order to solve for the molality and mole fraction of the solution. In order to determine its molarity, you're going to need the solution's volume.

To get the volume, you have to know what the density of the solution is. Determine the percent concentration by mass of the solution first

%w/w=msolutemsolution⋅100

In your case, the mass of the solution will be

msolution=mglucose+mwater

msolution=20+150=170 g

This means that you get

%w/w=20g170g⋅100=11.8%

The density of this solution will thus be

Answer 2

Answer:

If density of material of body is equal to density of liquid, the body floats fully submerged in liquid in neutral equilibrium. 3. When body floats in neutral equilibrium, the weight of the body is equal to the weight of displaced liquid.08
