How many milliliters of 0.258 M NaOH are required? This question delves into the realm of chemistry, where understanding molarity and its implications is crucial. This guide provides a comprehensive exploration of this topic, unraveling the intricacies of NaOH concentration and guiding you through the calculations to determine the precise volume of NaOH solution needed.
Molarity, expressed in units of moles per liter (M), serves as a measure of the concentration of a solution. In the context of 0.258 M NaOH, this signifies that every liter of the solution contains 0.258 moles of NaOH. This concept forms the foundation for calculating the volume of NaOH solution required for a specific mole amount.
Understanding the Concentration of NaOH
Molarity is a measure of the concentration of a solution, defined as the number of moles of solute per liter of solution. 0.258 M NaOH solution contains 0.258 moles of NaOH per liter of solution. The molarity of a solution is directly proportional to the number of moles of solute present in a given volume.
Calculating Milliliters of NaOH Required
To calculate the number of moles of NaOH required, use the formula: moles of NaOH = desired concentration (M) × desired volume (L). To determine the volume of NaOH solution needed, rearrange the formula to: volume of NaOH (mL) = moles of NaOH / molarity (M).
Substitute the known values and convert milliliters to liters to get the final volume.
Step-by-Step Procedure:
- Determine the moles of NaOH required.
- Substitute the values into the formula: volume of NaOH (mL) = moles of NaOH / molarity (M).
- Convert milliliters to liters by dividing by 1000.
- Calculate the volume of NaOH solution required.
Creating a Table for Volume Calculations
Table: Volume Calculations for NaOH Solution
| Moles of NaOH Required | Volume of 0.258 M NaOH Solution (mL) | Steps for Calculating Volume |
|---|---|---|
| 0.001 | 3.88 | 0.001 moles / 0.258 M = 0.00388 L; 0.00388 L × 1000 mL/L = 3.88 mL |
| 0.01 | 38.8 | 0.01 moles / 0.258 M = 0.0388 L; 0.0388 L × 1000 mL/L = 38.8 mL |
| 0.1 | 388 | 0.1 moles / 0.258 M = 0.388 L; 0.388 L × 1000 mL/L = 388 mL |
