  1. It depends upon what 1:2 means. There is confusion among even experienced on this. If 1:2 means 1 part NaHCO3 + 2 parts water, then the concn is
    0.6M x (1/3) = ?

    If you mean 1 part NaHCO3 + 1 part (to make 2), then the concn is
    0.6M x (1/2) = ?

    The following is a good web site to read, especially the last part of the post in which the difference between "factor" and "ratio" discussed.
