You had to calculate the mass of butanol for a certain reaction.

I got something like around 2300-2400g. You had to convert to kJ after the first part because it was kJ/mol. I think groovy grace we got the same answer but you didn't change to kJ?

I'm really not sure, thats what i think anyway.


wait so is 2.32g wrong? I got that too

Got that too! What did everyone get for the multiple choice about chloroethane? Options were SOCl2, PCl5, Cl2 in sunlight or NaCland H2SO4

I think it is but thats just my opinion. It was kJ/mol and you all did 84000J and not 84kJ so when you divided to get moles we got different answers.

There's a good chance I'm totally wrong.

I went for NaCl though I'm pretty sure I got 9/10 in MC, so I'll take that! I thought it was one of the easy exams they've brought out!
