Wouldn't it be 1.065 Kg?


One million grams is eqv. to one thousand kilograms.
what did people get for empirical formula?

I hope this helps clarify anything :smile:
I wasn't sure of the answer either


I wrote Argon as well, but out of stupidity because I thought the last question was about sulfur the next one couldn't possibly be about sulfur too. There is a larger jump from 6 to 7 in sulfur in comparison to argon, that's why I don't think it could be Argon. I just hope writing argon doesn't make us lose all the marks.

I ****ed up, coz i got 1.51 when i calculated copper, so i rounded it up to 2 instead of doubling

I somehow doubt it.. That should have been addressed before you went in, not just when you get a question wrong


I know, I only realised after when I looked at the packet details. I thought my vision was a bit blurry because I was so nervous and slightly nauseous . But that was the only one I had on me

thats correct either way, its 1065 000 000 grams, and you divide by 1000 to get kg, all good

Is cracking conditions 700kpa or 7000kpa?


7000 kPa
Yeah that's it in grams, if you divided it, it would have been in kg

Yeah I got that then multiplied them all by 2
I got 1.51 for copper, then multiplied everything by 2

I wrote argon too, we'll definitely lose all the marks. If you write the wrong thing the mark scheme says CE = 0 meaning you can't get any marks if you write the wron answer even if your explanation is justifiable
does anyone remember how many marks each of the questions were worth?
