O 146.7297 amu
0.9935 amu
0.2397 amu
0.4793 amu

i'm assuming that the correct answer is indeed the first one/ "a"..

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
