# Question #f76b6

##### 1 Answer

#### Explanation:

The idea here is that you need to figure out how many milliliters of the *stock solution* will contain the amount of sucrose that must be present in the *target solution*, i.e.

In fact, you don't even need to worry about the volume of the target solution in your calculations.

So, you know that your stock solution contains **per** *conversion factor* to help you find the volume of the stock solution that would contain

#0.25 color(red)(cancel(color(black)("g sucrose"))) * "100 mL solution"/(5color(red)(cancel(color(black)("g sucrose")))) = color(green)(|bar(ul(color(white)(a/a)"5 mL solution"color(white)(a/a)|)))#

This means that in order to prepare your target solution, you must start with

This is equivalent to **diluting** the

#"D.F." = (1000 color(red)(cancel(color(black)("mL"))))/(5color(red)(cancel(color(black)("mL")))) = 200#

The *dilution factor* is calculated by dividing the **volume of the diluted solution** by the **volume of the stock solution**.
