The volume remains the same.
The amount of solvent increases.
The concentration increases.
Answer:
about 200 calories of heat must be added to 1 gram of ethanol to convert it from a liquid to a gas
Explanation:
The mass of 4.35 ×10⁶ atoms of carbon-12 atom is 8.668×10 g.
A mole is a standard specific unit prescribed for measuring large quantities of entities which are very small such as atoms, molecules.It represents large number of units that is 6.022×10²³.
It was previously defined as the number which were experimentally determined to be found in 12 grams of carbon-12.Number of atoms in a mole is same for all substances.
Concept of mole provides quantitative information as to what happens in chemical reaction at a macroscopic level.It is used for determination of simplest formula of a compound.
For all practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons.

(1) copper (II) chloride
(2) aluminum acetate
(3) iron (III) hydroxide
(4) potassium sulfate
Iron (III) hydroxide is the least soluble compound as it has the lowest Ksp value.
The solubility is the amount of solute that can dissolve in a given volume of solvent at a particular temperature.
The solubility of substances can be compared using their their solubility products constant (Ksp) values.
Iron (III) hydroxide has the lowest Ksp value.
Therefore, Iron (III) hydroxide is the least soluble compound.
