A simple dilution problem.

  1. Sep 12, 2009 #1
    This problem seems simple enough, yet my professor says my answer is incorrect. Here is the problem.

    1 ml of a 0.10 M solution of HCL is added to 21 ml of distilled water. What is the final concentration of the solution (M)?

    Im going to use the equation

    C1*V1=C2*V2

    Where C1 is the initial concentration (M) and C2 is the final Concentration, and V1 is initial Volume, and V2 is final volume

    If I add 1ml of HCl to 21ml of H2O, I will have 22ml of solution. This is V2, therefore

    C1V1/V2=C2

    (0.1M)(1ml)/(22ml)=C2

    C2= 0.0045 M

    What am I overlooking?

    Thanks in advance.

    Perhaps s/he is nitpicking on the significant figures.
