Re: Cambridge Chemistry ChallengeI am still stuck on this. :/(Original post by dream_merchant)
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
Spoiler:ShowI've got 0.0045 g/dm^-3 and divided it by 305.41. Is that wrong? D: I am feeling sufficiently stupid.
