In standard weight box used for calibration of analytical
balance there are two numbers (Qty) of 20mg, 200mg,2.oGM
weights. Why?
Answer Posted / g. subrahmanyam
In standard weights box we receive single 1 mg, 2 mg, 5 mg, 10 mg, 50 mg, 100 mg and 500 mg, 1.0 gram, 5.0 grams, 10.0 grams and 100.0 grams weights. But we will receive two numbers of 2.0 mg, 20.0 mg, 200.0 mg, 2.0 grams, 20.0 grams and 200.0 grams weights in the box.
In order to weigh 4 mg, 9 mg, 14 mg, 25 mg, 34 mg, 44 mg, 54 mg, 64 mg, 74 mg, 84 mg, 94 mg, 104 mg, 19 mg, 29 mg, 39 mg, 49 mg, 59 mg, 69 mg, 79 mg, 89 mg and 99 mg we require two numbers of 2 mg in combination with other weights. Similarly the above same case apply with 20 mg, 2.0 grams, 20 grams and with 200 grams when we go the above level.
