Question

calculate the chemical formula and Molecular mass of sodium arsenate and ammonium zincate

Answer 1

Sodium arsenate - Formula: Na3AsO4

                              Molar mass: 207.8885 g/mol

ammonium zincate - Chemical formula : Na2ZnO4H4

                                   Molar mass : 179.418 g/mol

Answer 2

Chemical formula of sodium arsenate is Na2AsO4 and its mosecular mass is 207.88g/
mol
chemical formula of ammonium zincate is (NH4) 2 Zno2 and its molecular mass is 133.408g/mol
