I think you can get 1 or 2 marks for the working out, but you won't for the negative sign because in previous mark schemes it has said 'ignore signs', but if your working is correct and leads to the answer you put, even if it's wrong, I think you should still get 2/3 :smile:


cheers mate!

Didnt it ask for the amount of Centimetres squared of ethanoic acid, but beforehand it had given us the amount in decimetres squared…

I therefore wrote the answer as 1.2g because it should be ten times smaller.. surely?


however it asked for 250cm cubed so it would be a 1/4 of 48g so 12, because 1000cm cubed is a decimeter
