text: Dilution formula:  C1 x V1 = C2 x V2\n\nAs long as both concentrations (C) are the same unit and the volumes (V) are the same unit you can use that formula for any dilution.\n\nex.  How many mL' s of 0.1M HCl are need to make 10mL of 0.08M?\n\n C1= 0.1  V1 = x   C2= 0.08  V2 = 10 mL\n\n0.1x = (10)(0.08)\n     x = 0.8 mL\n\nSo, you would use 0.8 mL of the 0.1M HCl and add 9.2 mL of water to make 10 mL's of 0.08 M.
