Glycerol has a density $1.263$ g/mL. It is miscible with water in all proportions. So by changing the ratio glycerol:water, you can make a large number of mixtures having all possible densities between $1.263$ and $1.000$ g/mL. And all these mixtures are made of polar molecules. On the other hand, you may make up all sorts of mixtures with non polar ...

There is not enough information to decide, and the question is not clearly worded. As to the wording, "two volatile solutions (ideal) of pure liquids P and Q respectively," implies there is no vapor present, yet "vapours can travel through". What is the volume of each volatile liquid, and the total volume of the containers, including the ...

Water molecules in gas phase collide and are absorbed by both solutions at the same rate, assuming the same humidity over the solutions. OTOH, as sugar solution has lower molar fraction of water than water itself, its rate of water evaporation is lower than pure water evaporation. Therefore, there is the net transfer of water molecules from the water beaker ...
