You are given a 25.0mL volumetric flask, describe the procedure you will follow in lab to prepare 25.0mL of a 0.019 M solution of NaCl?

  • chemistry -

    Firstly you have to weigh the NaCl.
    Secondly put the weighed NaCl into the volumetric flask.
    Lastly after you've put NaCl into the container, add H2O up to 25ml mark.
