Day 167

Today, you will look at molarity from a different perspective...we will start with a known concentration that we want to make, and describe 2 different ways to determine how to make such a solution.  The first method will use the molar mass of the solute, the desired volume to be made and the concentration to determine how to create a solution from a solid solute; the second method will allow us to calculate how much a concentrated stock solution must be diluted to create a less concentrated solution.
