Calculation Molar of HCL 37%

  1. Apr 2, 2007 #1
    I have 1 bottle of HCL 37% Concentration with 2.5L Volume. Given the MW is 36.46g/mol. How to calculate the molarity of the HCL in the bottle? as i only need to prepare 1M of HCL?

    :confused: no density and molarity given in d label

    Was that 1 MOLAR or 1 MOLAL concentration that you wanted to prepare? In case you wanted MOLAR, then you need the density or specific gravity of the HCl 37% solution. Are you permitted to look for this value in a table of values, like in a handbook?

    What kind of label do you have? A professional, commercial label from a company? No matter.... you can simply look for 37% HCl in a handbook to find the specific gravity of this concentration. I'm assuming that this is a laboratory task and not a question-for-credit task.

    One more thing: since you had to ask your particular question, and it may be a practical question, DO NOT PIPET BY MOUTH. USE A PIPET BULB. In case you already know this, then please excuse this instruction, since you would use a bulb anyway.

    And use a fume hood. That is above the azeotropic concentration and has a lot HCl pressure
