Identify the type of problem: This is a dilution problem where you need to find the volume of a concentrated solution required to make a diluted solution.
Use the dilution equation: \( C_1V_1 = C_2V_2 \), where \( C_1 \) and \( V_1 \) are the concentration and volume of the stock solution, and \( C_2 \) and \( V_2 \) are the concentration and volume of the diluted solution.
Substitute the known values into the equation: \( C_1 = 14.8 \text{ M} \), \( C_2 = 0.250 \text{ M} \), and \( V_2 = 1000.0 \text{ mL} \).
Rearrange the equation to solve for \( V_1 \): \( V_1 = \frac{C_2V_2}{C_1} \).
Calculate \( V_1 \) using the rearranged equation to find the volume of the stock solution needed.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Molarity (M)

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. It is expressed in moles per liter (mol/L) and is crucial for understanding how much solute is present in a given volume of solution. In this question, the molarity of both the stock solution and the desired diluted solution is essential for calculating the required volume of the stock solution.

Molarity Concept

Dilution Equation

The dilution equation, often represented as M1V1 = M2V2, relates the molarity and volume of the concentrated solution (M1 and V1) to the molarity and volume of the diluted solution (M2 and V2). This equation allows us to determine how much of the concentrated solution is needed to achieve a specific concentration in a larger volume. Understanding this equation is key to solving the problem presented.

Volume Conversion

Volume conversion is the process of changing units of volume, such as from liters to milliliters. Since the question requires the final volume in milliliters, it is important to be comfortable with converting between these units. Recognizing that 1 liter equals 1000 milliliters is essential for accurately calculating the volume of the stock solution needed for dilution.
