Question

An analytical balance has uncertainty in measurement equal to plus minus 1 milligram

Answer 1

Step-by-step explanation:

We know that, 1 Gram = 1000 Milligram.

It is given that, the weight of the compound = 10 g = 10000 mg

Uncertainty in measurement of the analytical balance = plus or minus 1.

Therefore, Result = 10000  mg

Percentage of 1 mg in 10000 mg  = 1/10000 * 100=  0.01 %

In terms of percentage, Result will be 10000 mg ± 0.01 %
