你們覺得Chem的mole難不難?

我覺得普通.
明天我有chem test,是mole concept(F.6的東西)

有些是講述 Redox Titration.不過我老師出的mole,很難!不直接的.明知只計一compound的百分比.有齊包含的Chemical.還有計HCL.我真是不知那個HCL 's Function.

mole=f.6?

I did MOLES in f.5!
Did loads of titration last year@@|||
Had to repeat the same stuff this year because MOLES is in A-level syllabus too!
Bored.

As long as you remember the formula, moles is not difficult.
Because you can use "change of subject" to calculate in anyway round.

mole算係容易嗰d chapter啦
大把chapter仲難過mole
可能自己鍾意計數

同意, 我認為只要記實D工式, 就好易, 萭變不離其中

moles?
唔係form4開始教咩
我而家學緊
依課好似幾無聊....

Ya, its only calculating with the SAME formula

鬼鬼

我Form4都學左 計Mole囉！

總之記住物質不滅，Number of Mole = Number of molecule係不變，咁就得。

幾易喎
都唔難
要背ge野又少

不知 relative molecular mass=molar mass or not,

relative molecular mass數值同molar mass 相同...但relative molecular mass係冇unit....
回topic...中四中五D mole concept係算易..有D長equations仲難
(e.g. XYZ--->ABC--->GHI)
廢事think條equation..但有D organic reaction係咁煩= =
