minimum weight you can measured is called least count of
the analytical balance.By weighing subsequent low weights ,
at which level the weight is not deviating from the
standard weight by 0.01% ,that should be considered as
least count.For denver analytical balances it is 20 mg, for
micro balance is 0.01mgand for pan balance it is 2 gram

The least count of the balance has been given in the balance
itself.Otherwise place the weight in the balnce and check
the result in the balance.If the result shows for 1kg i.e
1.001 then the lease count of the balance is 0.001kg.

i think its 1mg and high weight is 220g as per my lab balance

What will be the effect on HPLC analysis result if three
mobile phases given separately through three valves and same
proportion mixed together and given by one valve?

In Number of Theoretical Plates (N) = 16 (tr/w)2.
where tr: retention time, and W: peak width.
My Question is here in formula what is 16.Can u explain
briefly?
