[Microbiology]: Is it 122,000 or 1,220,000?

I'm a bit confused. I hastily wrote 122,000 (you can see the work), but I have second thoughts and think that it is 1.22 million because you are also taking only .1 mL from the last tube, so I think I forgot to multiply by 10?

Im confused if Organic chemistry tutor made a mistake because this seems like its obviously R. OH is 1, CH2 wins CH3, and even swapping the H and CH 3 would still have both the 1 and 2 in the same position, so wouldn't it still stay R?

So this chiral calculator says red is chiral with R configuration, blue is chiral with S.

But I'm confused how they are chiral centers. Both the red and blue have a CH2 attached, so wouldn't that mean it is the same group therefore they are not chiral centers?

What rule should I follow to know they are chiral centers in case of these types of structures?

Question says: Draw the important resonance forms of the following free radicals.

This was a practice question we were given for a chapter. I just want to ask if these are correct (especially D and E hence the question marks).

The original is the one closest to the letters and the resonance are any ones after.

I drew some full arrows by accident and felt too lazy to erase them, but just pretend the one at F is a half arrow (I know they're supposed to be half arrows, muscle memory kicked in sometimes).

Ignore the stick figure lol
