I know it's the wrong answer, but at least I am not the only one who wrote gloves

Well if u compare previous MS with the current ones there is a difference..
The new ones have many possible answers!!
Hope for the best!!

no.

Really? Because in my case the calculations are always incorrect even if i round them to three significant figures.
Anyways the 39.2 WAS obviously supposed to be rounded.

This time in the paper i checked my answers to see whther there was any difference if i DIDNT round things up. Hardly any difference, something like a difference of 0.0003 or something. For example, in part (e) of the moles question, i got something like 0.00237 (i dnt really remember, cud be different) so i rounded it off to 0.0024.

For that safety item in the reflux condenser....I put pipette filler to prevent liquid entering mouth.....is it correct????

Relative molecular mass is always supposed to be in whole number. Chlorine is an exception.

ook at the alevel periodic table the MR is in points too so nt a big deal by 39.2
