Homework Help: A level Chemistry relationship between

  1. Apr 21, 2010 #1
    1. The problem statement, all variables and given/known data

    Write an equation in words to show relationship between mass concentration, molar concentration and molar mass and give an explanation.

    2. Relevant equations

    Not sure :/
    This one has popped up a few times, A=M/Mr, but as of this moment I am not sure of what the letters stand for.

    3. The attempt at a solution

    My Chemistry teacher gave this question as a homework yesterday. After looking through text books and my notes I cannot find a word equation involving the mass concentration, molar concentration and molar mass, let alone an explanation for their relationship...

    This question was given after a practical session where we attempted to determine the concentration of NaOH from a standard solution of known concentration.

    Thank you for any help you can give on this question :smile:

    Hwo do you convert mass to moles?

    Number of moles = number of grams/molar mass

    What is mass concentration? Molar concentration?
