This is a really rough approximation based on the atomic numbers in my head....
2 (22.9gNa) + 32gS + 3 ( 16gO) = 125.8g is the molar mass of Sodium sulfite

The chemical formula of sodium chloride is NaCl.
The formula mass of sodium carbonate, Na2CO3 is 2(23.0)+12+3(16) = 106.0Amount of sodium carbonate = mass of sample / formula mass = 4/106.0 = 0.0377mol
The gram atomic mass of sodium is 22.9898, the formula of the least hydrated form of sodium phosphate is Na3PO4.10 H2O, and the gram formula unit mass of this sodium phosphate is 344.09. Therefore, the mass fraction of sodium in this sodium phosphate is 3(22.9898)/344.09 or about 0.20044, and the grams of sodium in 7.2 grams of this sodium phosphate is 1.44 grams of sodium, to the justified number of significant digits.
The chemical formula for tin sulphite is SnSO3.
The chemical formula for calcium sulphite is CaSO3
