Ok There should be a photo in here...hopefully. Or attached.

My question is where did the 1.66x10^-27 come from.

1 AMU = 1.66 x 10^-27kg we have to know this one?

they would give you that value most lilkely. On the DAT, I highly doubt they will ask you to carry out the full calculation.

You should know the general concept of mass defect and nuclear binding energy.

Ex. Higher the nuclear binding energy pernucleon, more stable the atom is and less likely to be radioactive.
