omg first go at trying these and I suck so bad at working them out. On the second level. Is it points on a map? Oh dear I'm so bad at this -.- why does it say relative molecular mass?
Any help with Rg please? I've been looking at the same thing for a while, and it's not clicking into my head how I should go about this :frown:
