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. :/ :frown:

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 :frown:
