Today read through the notes (Atoms,Moles and Stoichiometry)
i felt that it similar to physics!!!!
like basic quantities ,derived quantities and prefixes.
And different countries have different systems of units.I thought only chinese have their own unit of mass ,but after i read through the notes , found out that malay ,indian ,japanese ...have their own units too.
In chemistry, UNITS very important too!so we need to memorize all the units properly also.
I am very happy because i finally can determine the number of significant figures in number.
Maybe Ms Jee knew that alot of people cannot understand it well.= =

Hi Been Ting,
ReplyDeleteGlad to hear the explanation on significant figures is useful. By the way, there is a typo error in one example: 0.123000 has 6 s.f.
Cheers,
