    A would be true EXCEPT for the except part. As far as I know, absorbance values have significant figures also.
    B. I don't know that ALL numbers should be recorded.
    C is true.
    D is true.
    E can't right if C and D the only true ones.

    Absorbance doesn't have units, and you should record all the numbers in a digital readout, so all of them are true.

    E all of these are true

  • chemistry(can anyone help me with this) - ,

    E all of these are true
