I am hoping to receive help getting started with this problem, possibly some steps in the correct direction.

Here is the question: 5.0mLs of a 6.0M solution of HCl was transferred to a 1000ml volumetric flask and diluted to volume w/ water. 50mLs of this solution was then transferred to a 100mL flask and diluted to Volume with water. What is the molarity of the 2nd diluted solution?

  • Chemistry - ,

    Can some one check to see if I did this correct:

    6M= moles of solute/.005 L solution

    .03=moles solute

    M of2nd solu=.03 m solute/.05L solution

    M=.6

  • Chemistry - ,

    After the second dilution:
    M of2nd solu=.03 m solute/.10L solution

  • Chemistry - ,

    Why .10L

  • Chemistry - ,

    I based on this, unless I mis-read it.

    50mLs of this solution was then transferred to a 100mL flask and diluted to Volume with water...

  • Chemistry - ,

    Sorry, the second post was sent by mistake. No shouting intended! :)
