Capitolo 4, Problema 74b
(b) If you dilute 10.0 mL of the stock solution to a final volume of 0.250 L, what will be the concentration of the diluted solution?
Guida verificata passo dopo passo1
Identify the initial concentration of the stock solution, denoted as C1, and the initial volume, V1, which is 10.0 mL.
Recognize that the final volume, V2, after dilution is 0.250 L (or 250 mL).
Use the dilution formula: C1 * V1 = C2 * V2, where C2 is the concentration of the diluted solution.
Rearrange the formula to solve for C2: C2 = (C1 * V1) / V2.
Substitute the known values into the equation to find the concentration of the diluted solution, C2.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Dilution
Dilution is the process of reducing the concentration of a solute in a solution, typically by adding more solvent. The relationship between the concentrations and volumes of the stock and diluted solutions can be described by the dilution equation, C1V1 = C2V2, where C1 and V1 are the concentration and volume of the stock solution, and C2 and V2 are the concentration and volume of the diluted solution.

Dilution Equation
Concentration
Concentration refers to the amount of solute present in a given volume of solution, often expressed in units such as molarity (moles per liter). Understanding how concentration changes during dilution is crucial for calculating the final concentration after mixing different volumes of solutions.

Volume
Volume is a measure of the three-dimensional space occupied by a substance, commonly measured in liters (L) or milliliters (mL). In dilution calculations, the initial and final volumes are essential for determining how the concentration of a solution changes when additional solvent is added.
