You are provided with a 1M aqueous solution of a compound. How would you produce 10ml of a 200mM solution?

Question

wolfe8 · Answer

Well first you will have to dilute that. Use the formula $$m _{1}V _{1}=m _{2}V _{2}$$

kamille · Answer

I know c1, v2 and c2?

wolfe8 · Answer

I'm assuming c is molarity. Then yes, something like that. You want to know how much distilled water you want to add to the concentrated solution.

kamille · Answer

hm, c is concentration

kamille · Answer

is it the same?

wolfe8 · Answer

Concentration in terms of molarity for this case. :) You can have concentration in the terms of gram/liter as well

wolfe8 · Answer

Molarity being mol/liter

kamille · Answer

so I get:
v1=0,2*0,01/1=0,002l

wolfe8 · Answer

Then that should be the volume of the 1M solution you will takes and add distilled water until you get 10ml of solution. You can find how much distilled water you will add. If I'm doing this right.

kamille · Answer

so I will need to take 2ml and add 8ml of water? Thanks.

wolfe8 · Answer

Sounds about right. You're welcome.
