**Question: What is the definition of molarity in chemistry?**

**Molarity measures the total number of moles in a given solution.**- Molarity is the concentration of a solution expressed in grams.
- Molarity represents the volume of a solution in milliliters.
- Molarity measures the number of particles in a solution.

**Answer: ****A) Molarity measures the total number of moles in a given solution.**

## Define Molarity Solution:

In the realm of chemistry, **molarity** is a fundamental concept that quantifies the concentration of a solute in a solution. It is crucial to understand what molarity truly means.

- Define Molarity as
**the measure of the total number of moles of a solute dissolved in 1 liter of solution**. This measurement allows chemists to express the concentration of a substance in a consistent and easily quantifiable manner. - The correct option,
**Option A)**, correctly defines molarity by highlighting that it quantifies the number of moles of the solute. - Understanding molarity is, therefore, a fundamental aspect of chemistry.

## Dimensional Formula Of Surface Tension

The **dimensional formula of surface tension** represents the physical dimensions of this property in terms of fundamental quantities. The dimensional formula of force is $[MLT_{−2}]$, and that of length is $[L]$. Hence, the dimensional formula of surface tension is $[MT_{−2}]$. This formula provides insight into how surface tension varies with different physical quantities.
