Question 911395: A mole is a strange unit of measurement giving the amount of a substance that contains 6.022*10 to the 23 power. The molarity is a concentration measured in moles per liter. You have a solution with a molarity of 10to negative 3 power moles/L and need 10ml at 10 to negative 4power moles/L. What do you do?

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%28%28CONCENTRATION%29%28VOLUME%29=MOLES%29.


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

%280.001%29%2Av=%280.0001%29%2810%29

v=%280.0001%29%2810%29%2F%280.001%29

highlight%28v=1%29


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.
