a.

anonymous · Answer

c. and d. are incorrect forms of S.N., therefore the remaining choices are a. and b. From which I deduce the answer is //b.//

anonymous · Answer

if you believe b, you will miss it. ask anyone with knowledge of chemistry they will tell you AMU = 1.66x^10-27 and the charge of an electron is 1.6x10^1.9 coulombs

anonymous · Answer

I would say A just based on the fact that the units are included.  (kg and C)
