Calculate the mass of 2.18 x 10^22 molecules of B2H6? Show your work!!!

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

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
