In today's class we did a lab. In this lab we had to find out which of the 5 test tubes with Copper (II) Chloride in it had a concentration of 2.0M.
The procedure we used was to first find out the molar mass of Copper (II) Chloride, then using the mass we found, we divide it by the concentration given, to find the amount of water needed to dilute the Copper (II) Chloride into.
Using these calculations, we diluted 3.0g of Copper (II) Chloride into 111.5 mL of water, giving us a concentration of 0.2M.
