    dude it's one thing to ask for general help, but asking people online to DO your homework? that's just ridiculous and will just end up hurting him in the long run anyway

    stoikiometry was the worst thing in the world.

    also my teacher was incapable of teaching.

    Re: Chem Pre Lab Assignment -HELP

    J.P.:
    if 0.1034g of ferrous ammonium sulphate hexahydrate is dissolved in water and made up to 1L of solution in a volumetric flask,

    a) what mass of ferrous ion is pressent in 1L solution (in grams)

    b) what is the iron concentration of this solution? (mg/L)

    molar mass of ferrous sulphate hexahydrate= 392.13 g/mol

    the answer is "yes".

    probably*

     

     

     

    *probably not.

    Use the molecular weights, and then the two basic formulas, n = m/M c = n/v

    good luck

    I have had a hard time believing that you were 15 as you have said before....Now I`m totally baffled...Well done

    note..the only chemistry I learned was that you have to be very careful to get the right doseage when mixing your acid and mescaline intakes...
