Thanks for providing the numbers. I don't know what you did wrong but here is how you do it. Pay particular attention to the "how to do it" after you obtain the right number.
c1v1 = c2v2
200mL x 0.15M = 1.00M x v2
v2 = (200 x 0.15/1) = 30 mL.
Take 30.0 mL of the 1.00 M stock solution, place in a 200 mL volumetric flask (we'll assume they make such things), and add water to the mark.
You're working with volume; therefore, weighing is not the right word to use. Also, note that your 33 L (that isn't right) but it is converted to mL correctly either. 33 L = 33,000 mL and you should have thought something was wrong since you started out making 200 mL TOTAL volume.
Describe in detail by words how to prepare 200ml of .150M HCl from a 1.00 M HCl stock solution? Need help with this please?
i used C1V1=C2V2 and got volume 2 = 33L or 0.33mL.
to prepare the solution i need to weigh 1 gram of HCL (from 1.00M HCl stock solution)lets say i put it in a graduated cylinder, then i put the right amount of stock solution or water i'm confused until it reach the mark .33mL. pls pls check my answer thank you
