What is the minimum mass of the sample for analysis

Reference no: EM13719627

Question- A sample contains about 25% of the ion A2- . A2- is determined by precipitating the compound M2A. M has an atomic weight about 3.5x that of A. If the uncertainty in determining the weight of the precipitate is not to exceed 1% on a balance accurate to 0.1 mg, what is the minimum mass of the sample that should be taken for analysis?

I need proficient help to explain each and every step in detail of the above problems.
