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.

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