Edexcel AS Chemistry Practicals

I just did my calculations and I forgot to round my values to 3 sf and I also forgot to put units.

Will I get marks knocked off for these even though my answers are correct? :eek:

Yes, you'll lose marks for no units. You might not lose marks for the significant figures if the question didn't state "3 s.f."

it said (to appropriate sf) but i simply just put everything i saw on the calculator onto the answer sheet..

so i lose marks for no units? even though the answer only worth 1 mark? does it mean that i will get zero even though my answer is right?

If it was only 1 mark then you won't lose marks for unit. But yes, you will lose the mark for significant figures, sorry.

Edexcel ISA markschemes are actually quite mean.
I remember last year I forgot to put sig figs etc and I dropped so many marks!
You've probably dropped at most 2 marks.

EDIT: If they said "state your units" then yes, you would lose a mark for it.
