# To what volume should you dilute 0.200 L of a 18 M HCl solution to obtain 1.0 M HCl?

## Question:

To what volume should you dilute 0.200 L of a 18 M HCl solution to obtain 1.0 M HCl?

## Dilution Equation:

The dilution equation is often used to determine the volumes and concentrations of a stock solution to prepare a more dilute solution. Aside from acquiring these values, the dilution equation also shows that the moles of solute present does not change. Dilution is a technique that involves adding solvent to a certain volume. As a consequence, the moles of solute remains unchanged. The dilution equation is written as:

solution. The equation for dilution is given below.

{eq}\rm C_1V_1~=~C_2V_2 {/eq}

Where:

• C1 is the concentration of the initial solution
• C2 is the concentration of the final solution
• V1 is the initial volume of the solution.
• V2 is the final volume of the solution.
