For this stage you must read the concentration of Capsaicin in ppm from the graph (must first log10 the 500000 SHU and then doing 10^(y-value)) then convert ppm to moldm-3


I've been doing that, but I realised that when I converted, I divided by 100 instead of 1000. :tongue: Thank you! :biggrin:
Yay! I solved them all a while ago, woooo. :biggrin: Thanks CM23925 for that tip. :smile: YAY When I solved Roengentium, I felt so silly because I realised how obvious it was. :P YAY

It was something beginning with E, and there were several scientists on the case, fairly recent.

Hurry then you can return the favour with gold because I'm having a blonde moment. Even though I'm Asian and have dark hair. :P

Degreen, it took me a while. It's a weird hydrocarbon, like a really weird one.
