Introduction

Preparing diluted solutions is a crucial step in various scientific experiments, including chemistry and biology. Diluted solutions are used to achieve specific concentrations of substances, which can be essential for accurate results. In this article, we will discuss how to calculate the initial volume needed to prepare each of the following diluted solutions.

Calculating Initial Volume for Diluted Solutions

To calculate the initial volume needed to prepare a diluted solution, we can use the formula:

Initial Volume (V1) = Final Volume (V2) x Concentration of Stock Solution (C1) / Concentration of Diluted Solution (C2)

Where:

V1 is the initial volume of the stock solution
V2 is the final volume of the diluted solution
C1 is the concentration of the stock solution
C2 is the concentration of the diluted solution

Example 1: Preparing 250 mL of 3.30 M H2SO4 from 16.1 M H2SO4

To prepare 250 mL of 3.30 M H2SO4 from a stock solution of 16.1 M H2SO4, we can use the formula above.

First, we need to identify the values given in the problem:

V2 = 250 mL (final volume of the diluted solution)
C1 = 16.1 M (concentration of the stock solution)
C2 = 3.30 M (concentration of the diluted solution)

Now, we can plug these values into the formula:

V1 = V2 x C1 / C2 V1 = 250 mL x 16.1 M / 3.30 M

Calculating the Initial Volume

To calculate the initial volume, we need to perform the division and multiplication operations.

V1 = 250 mL x 16.1 M / 3.30 M V1 = 1220.61 mL / 3.30 M V1 = 366.85 mL

Therefore, the initial volume needed to prepare 250 mL of 3.30 M H2SO4 from 16.1 M H2SO4 is approximately 366.85 mL.

Conclusion

Preparing diluted solutions is a critical step in various scientific experiments. Calculating the initial volume needed to prepare each of the following diluted solutions requires careful consideration of the concentration of the stock solution and the final volume of the diluted solution. By using the formula V1 = V2 x C1 / C2, we can accurately determine the initial volume needed to prepare each of the following diluted solutions.
