Please determine the accurate answer of the given Problem
Problem-A 3.00-g sample of an alloy (containing only Pb and Sn) was dissolved in nitric acid (HNO3). Sulfuric acid was added to this solution, which precipitated 2.58 g of PbSO4. Assuming that all of the lead was precipitated.
Part 1- What is the percentage of Sn in the sample? (molar mass of PbSO4 = 303.3 g/mol).
I want expert's assistance to find the percentage of Sn in the sample.
