The given statement is false.

The mole is an SI unit used to measure amount of any substance. It is defined as the amount of a substance that contains the same number of entities as there are atoms in exactly 12 g of carbon-12. One mole is equal to 6.022× 10^-3

A mole of one substance has a same number of units as a mole of other substance.

Theoretical yield is the amount of the product formed in a reaction. Theoretical yield is calculated based on the stoichiometry of the chemical equation. While the actual yield is experimentally determined.

The limiting reactant is the one which is entirely used in the reaction. Limiting reactant limits the formation of products.

A limiting reactant problem is the one in which the stoichiometric ratio of the reactant is not given.

Molarity expresses the concentration in units of moles of solute per litre of solution.

$\text{Molarity =}\frac{\text{moles of solute}}{\text{litres of solution}}$$\text{Molarity =}\frac{\text{moles of solute}}{\text{litres of solution}}$

$\begin{array}{rcl}& & \text{Molarity of NaCl =}\frac{3.00\text{moles of NaCl}}{\text{1 litre of solution}}\\ & & \text{= 3 M}\\ & & \end{array}$

An intensive property is the one that does not depend on mass of the substance.

An extensive property is the one that depends on the size and amount of the matter in thesystem.

Concentration is an intensive property because the ratio of the amount of solute to total amount of solution is same irrespective of the actual solution present.

Solubility is an intensive property that indicates the maximum amount of solute that can be dissolved into the solvent.
