Adobe InDesign 6.0 To calculate the concentration of the diluted solution (C2), you can plug these values into the dilution equation: Result: This means that the concentration of the diluted solution is 1.67 M. You have a solution with a concentration of C1 = 10 g/L and a volume of V1 = 50 mL. pP8AmZ0P9yz/ADyq33nI6f8Aorl+34q/5mdD/cs/zyl95yK/0Vy/b8Vf8zOh/uWf55S+85Ff6K5f /;/metadata 2013-06-20T11:28:19-04:00 f+3G/wB6SlftDp//AHJp/wC3G/3pKV+0On/9yaf+3G/3pKV+0On/APcmn/txv96SlftDp/8A3Jp/ 0000001409 00000 n xmp.iid:0247081A7A296811871FF8EAC8023FA4 What volume of stock will you a) 1.20 M. b) 1.50 M. c) 1.344 M. d) 2.70 M.
