Hi Haizo, let's look at how to prepare a diluted sodium hydroxide solution from a more concentrated stock solution.
Preparing a 300 mL 0.1 M NaOH Solution
First, let's identify what we know. We want to end up with three hundred milliliters of zero point one molar solution. This is our final volume and final molarity.
Given Information
- Required Concentration ($M_2$): $0.1\text{ M}$
- Required Volume ($V_2$): $300\text{ mL}$
We are starting with a stock solution that has a concentration of two molar. We need to find out how much of this stock solution we should use.
- Stock Concentration ($M_1$): $2\text{ M}$
To find this volume, we use the dilution formula: M one times V one equals M two times V two.
Now, let's plug in the numbers. Two molar times V one equals zero point one molar times three hundred milliliters.
