    NiSO4.7H2O, anyone (please)?

    My working found that it had 7H2O and obviously Ni, and I had the molar mass of the salt. So I found the molar mass of 2- ion in the salt and guessed it as sulphate. The molar mass of sulphate was actually 0.1 off of what I wanted it to be but I guess I made a rounding error somehwhere...

    You can't complain because you found the paper hard. All the papers have become harder of late, and boundaries are adjusted anyway.

    There will be a range of answers, probably between 0.4 and 0.5 or something.
