# Dilution Calculation?

After performing a dilution calculation, you determine you need 25.0 milliliters of an aqueous stock solution to make 100.0 milliliters of a new solution. How would this be prepared?

a) add 25.0 milliliters of the stock solution to a volumemetric flask, then add 100.0 milliliters of water.

b) add 25.0 milliliters of the stock solution to a volumetric flask, then add water to a total volume of 100.0 milliliters.

c) add the stock solution and water in equal amounts until 100.0 is reached

d) add 25.0 milliliters of water to a volumetric flask, then add the stock solution to reach a total volume of 100.0 milliliters.

Calculate the shape of moles of HCL you've interior the unique answer. Then divide the shape of moles by the finished volume you've on the right (525 + 102). be certain you substitute to liters, not milliliters.
