How many milliliters of 0.225 M NH4C2H3O2 are needed to make 750.0 mL of 0.1667 M NH4C2H3O2?

  • Chemistry -

    dilution formula

  • Chemistry -

    ok so did I do it right??

    0.225(750.0)=0.1667(v)
    168.75/0.1667=1012.3??

  • Chemistry -

    Isn't this the same as the above?
    0.225 x mL = 0.1667 x 750 mL.
    mL = ?
    The problem asks for "how many mL of 0.225M must ......."
    so you have the v (unknown) in the wrong place.
