Does molarity change if I add more solute?

Yes. Molarity is defined as $n/V$. By adding more solute, you increase the number of moles ($n$), which directly increases the molarity of the solution.

Is molarity temperature-dependent?

Yes. Since volume ($V$) expands or contracts with temperature changes, the molarity ($M = n/V$) will change slightly as the temperature varies.

What happens to molarity during dilution?

During dilution, you add solvent but the moles of solute remain constant. Therefore, the volume increases and the molarity decreases ($M_1V_1 = M_2V_2$).

Can molarity be greater than 10?

Yes, highly concentrated acids like sulfuric acid ($H_2SO_4$) have a molarity of approximately $18\text{ M}$, though most laboratory reagents are much lower.

Why use Molarity instead of Molality?

Molarity is much easier to use in a lab setting because it involves measuring volumes of liquid with glassware (flasks, pipettes) rather than weighing the solvent on a scale.

What is a 'Standard Solution'?

A standard solution is one whose molarity is precisely known. These are often prepared by dissolving a primary standard solute in a volumetric flask.

How does Density affect Molarity?

Density relates the mass of the solution to its volume. If you know the mass percentage and density, you can find how much solute is in a specific volume of solution.

What is the unit of Molarity?

The SI unit is $mol/m^3$, but in chemistry, we almost exclusively use $mol/L$, also denoted as $\text{M}$ (molar).
