Answer: Wax
Explanation:
Density is defined as the mass contained per unit volume.
Usually solids are more denser than liquid, as molecules in solid are more strongly packed and thus have more mass per unit volume.
Liquids on the other hand contain molecules which are less tightly bound and thus thus contain less mass per unit volume as compared to solid.
Example: Solid wax is more denser than liquid wax.
<u>Answer:</u> The molality of the solution is 0.1 m.
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:
Where,
= Given mass of solute = 27.1 g
= Molar mass of solute = 27.1 g/mol
= Mass of solvent = 100 g
Putting values in above equation, we get:
Hence, the molality of the solution is 0.1 m.
