Just wondering if you need to know this for preliminary: (2 Viewers)

It is to calculate molarity:

M= n/v

Molarity = number of moles/volume

Yes and you will need that for year 12 as well.

You'll learn it anyway, iirc.

i know we will need it for year 12. But i was introduced to it by a friend, and we have done nothing like it in preliminary.

You must know this - it's also quite obvious considering that molarity, M, has units mol/L.

It is to calculate molarity:

M= n/v

Molarity = number of moles/volume

To be picky, it's actually c = n/V. The capital 'M' stands for the units of molarity, but isn't used by convention to represent the aforementioned quantity itself. Also, 'V' is capitalised by the same guidelines.

Pointing it out because I would've lost a mark at baulko with that.

By losing a mark, do you mean the M or the V - I personally don't think a capitalised V would really make a difference but c and M should be penalised.

Both. The capitalised V is definitely a problem. By convention a small 'v' means velocity.

lol, that's physics though. I agree however, volume should be denoted by V not v.

No - the convention extends across all sciences!

What iSplicer said is correct, you can see for yourself here http://library.thinkquest.org/12354/gather/gasvnc.htm
