A minimum weight you can measured is called least count of
the analytical balance.

Answer / rajashekar reddy.v (dr reddys)
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

Answer / venkat-piramal
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.

Answer / ankit chaudhary
Least count is the unit count in which balance gives readings for example if 100 gm balance gives readings of 0.001 variation ,so its least count can be considered as 0.001 mg

Answer / pradeep
Least count is lowest value measure by any measuring instrument accurately. If a measuring ruler have divisions in Centimeter and milimeter then least count is 0.1 Centimeter or 1 mm. In case of instrument like balance least count given by instrument manufacturer because capacity of balance to measure lowest value is checked during it's manufacturing. If it's not given then it will be measure not get calculated. The lowest weight measured with accuracy of +/- 0.001% is consider as it's least count.

Answer / pharmgrow
Its soooo simple.
Least count is difference between two consecutive readings.
If two consecutive readings are 5.234 g and 5.235 g just find difference between them you will get least count. In this case least count is 0.001 g.

Answer / leela
least count = weight of spring balance/division
for ex- 20g/5=4 ans

Answer / somaji
least count formula = least count*100/0.1
maximum count maxiunm weight*80/100

why we make titiration of Iron with EDTA ?
I have compare C2H2-air and C2H2-N2O flame AAS on determination calcium. Both use same range of std to plot calibration curve. (2-6ppm) When i measure the sample with phosphate, KCl and LaCl, C2H2-N2O flame give false positive result, around 0.5ppm. When i measure the sample with phosphste, KCl and EDTA. C2H2-N2O flame also give 0.5ppm false positive. But both above mentioned sample would not give false positive when measured by C2H2-air flame. What is the reason?
