Which of the following statements is true?

Unsaturated solutions will not dissolve more solute.

For most substances, the solid state is more dense than the liquid state.

Density is not temperature dependent.

A nonpolar solute will dissolve in a polar solvent such as water.

For more substance the solid state is more dense than the liquid state.

Explanation:

Option B is true.

The substance in solid state are more dense than in liquid state because particles are tightly packed together.

while the case is different in water because ice is less dance than liquid water.

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL, kg/L

Formula:

D=m/v

D = density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Other options are incorrect:

Unsaturated solutions will not dissolve more solute.

Unsaturated solution can dissolve more solute until it reach to the saturated solution.

Density is not temperature dependent.

it is temperature dependent.

A nonpolar solute will dissolve in a polar solvent such as water.

Dissolution always follow like dissolve like. A non polar solute will dissolve in non polar solvent.
