How many liters of concentrated 18 M HCl is needed to prepare 225 L of a .66 M solution? 75 L 8.3 L 0.23 L 1.5 L

## Step 1The problem involves the concept of molarity and dilution in chemistry. Molarity (M) is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution.## Step 2The formula for dilution is given by , where and are the molarity and volume of the concentrated solution, and and are the molarity and volume of the diluted solution.## Step 3In this problem, we are given:- M (concentration of the concentrated HCl solution)- M (desired concentration of the diluted HCl solution)- L (volume of the diluted HCl solution)## Step 4We need to find , the volume of the concentrated HCl solution needed.## Step 5Using the dilution formula, we rearrange to solve for :### ## Step 6Substituting the given values:### ## Step 7Calculating this gives us the volume of the concentrated HCl solution needed to prepare 225 L of a 0.66 M solution.
