Atorsion balance has a sensitivity requirement (sr) of 4.5 mg. what is the mwq of this balance if the maximum error permitted in using it is 3.6%?

Explanation:

MWQ means the minimum weighable quantity.

Mathematically,         MWQ =

or,        MWQ =

It is given that sensitivity is 4.5 mg and maximum permitted error is 3.6%.

Therefore, fraction error = = 0.036

Hence, we will calculate MWQ as follows.

                  MWQ =

                            =

                            = 125 mg

Thus, we can conclude that the MWQ of the given balance is 125 mg.

is has three carbons, so the answer is propylamine.
