yeah i knw but i didn get what to do so i jus did it with normal moles..dey wil cut 1 mark
it was tricky
i did it by dilution as well. adding 200cm3 of the 25mmoldm-3 solution and 10cm3 of water to prepare a 20mmoldm-3 solution and so on. I wasn't sure if to use a solid or not because i felt that was more chemistry rather than biology as we would have had to calculate number of moles?
what do you think?
