(a) How many milliliters of a stock solution of 6.0 $\mathrm{MHNO}_{3}$ would you have to use to prepare 110 $\mathrm{mL}$ of 0.500 $\mathrm{M} \mathrm{HNO}_{3} ?$ (b) If you dilute 10.0 $\mathrm{mL}$ of the stock solution to a final volume of $0.250 \mathrm{L},$ what will be the concentration of the diluted solution?

Key Concepts

Molarity

Molarity is a measure of concentration expressed as the number of moles of solute per liter of solution. It is fundamental in preparing solutions of a desired concentration and for carrying out reactions in solution, as it directly relates the quantity of solute to the volume of the solution.

Dilution

Dilution involves adding solvent to a solution to decrease the concentration of the solute. The process is quantified by the dilution equation, which relates the volumes and concentrations before and after dilution, typically expressed as C1V1 = C2V2.

Conservation of Moles

The conservation of moles principle states that the number of moles of solute remains constant during a dilution process. This means that when a solution is diluted, while its volume increases and its concentration decreases, the total amount (moles) of solute does not change.

Unit Conversion

Unit conversion is an essential process in solution chemistry, ensuring that volumes and concentrations are expressed in consistent units. For example, converting milliliters to liters is often necessary because molarity is defined in terms of liters of solution.
