    i didnt use the density at all. you know the compound so you know the mr of the compound. so you mess aroiund with the numbers to change mg/dm3 to mol/dm-3
    I am still stuck on this. :/

    I've got 0.0045 g/dm^-3 and divided it by 305.41. Is that wrong? D: I am feeling sufficiently stupid.

    You're looking for three different metal atoms that occur in three different types of porphyrin (look at the pictures in the background)

    nope, does each line mean a letter, a group of letters, or each relate to an element to make a compound. its so confusing
