i think u lose marks because 2 sig figure is not accurate for experiments..i thiiink not sure how will the examiner deal with ur situation
Oh man :/ How much marks would I lose exactly? Each question was 1 mark! The total marks were like 8 marks!
u did 31 right ?
No actually I was talking about paper 21 - The number of moles question... I'm taking 32 in a week
ohhh that one..i think they will mark u on the method not the answer..so u might just lose the last mark for the percentage if u r inaccurate and stuff but it was gonna..if u did the correct methods then the examiner will understand that u know whats going on so to be fair u deserve marks on that..got me ?
Yup I did the correct method on each and every question, but when the answer was 0.79, i rounded it to 0.8 and so on. The only thing I rounded to 3 sf was the last bit. Everyone got like 43.3 or 43.4 while I got 44.6
no worries u might just lose a mark for not being accurate in ur answers...we all did silly mistakes in the paper. what did u write for the units for the pressure expression
I don't remember sorry... If you remember the number of moles on each side of the equation, then I can solve it again. I think it was Pa?
yeah i did the same mistake "pa" it was supposed to be Kpa because the units where given KPA not pa..tricky question
Really? :O OH SNAP :cyeah i did the same mistake "pa" it was supposed to be Kpa because the units where given KPA not pa..tricky question
nooooooooooooooo
It can't be, because there are 6 + 4 moles on the right side, and 5 + 4 moles on the left side. If it had to be in atm then it would be atm not atm^-1. But isn't it in Pa? The question was in Pa I was sure
unfortunately Kilo paIt can't be, because there are 6 + 4 moles on the right side, and 5 + 4 moles on the left side. If it had to be in atm then it would be atm not atm^-1. But isn't it in Pa? The question was in Pa I was sure
It was 9moles in the left hand side(denominator), and 8moles in the right hand side(numerator).It can't be, because there are 6 + 4 moles on the right side, and 5 + 4 moles on the left side. If it had to be in atm then it would be atm not atm^-1. But isn't it in Pa? The question was in Pa I was sure
We'll just have to wait and see, but I'm pretty sure I double triple checked number of moles
