Question 911395
Account for the number of moles.


Solution Available:  0.001 M


Wanted Solution:  10 ml at 0.0001 M


Your question should be, how many milliliters of the available solution should be taken to prepare the wanted-solution?  Use the idea, {{{highlight_green((CONCENTRATION)(VOLUME)=MOLES)}}}.



Let v be the amount of volume in milliliters to use from the available solution.


{{{(0.001)*v=(0.0001)(10)}}}


{{{v=(0.0001)(10)/(0.001)}}}


{{{highlight(v=1)}}}



To finish this, because the conditions to end with are to include final volume of solution of 10 milliliters, you want 9.00 milliliters of water with your 1.0 milliliter of stock/starting solution.
