What is the formula and mass of one mole for ammonium sulphate?
If the first person is right then ammonium sulphate’s formula is: NH3SO2 Relative Molecular mass (larger number above the symbol on the periodic table) N = 14 H = 1 (x 3 as there are three H’s) = 3 S = 32 O = 16 (x 2 as there are s O’s) = 32 Add them together: 81g for one mole If they aren’t right use the above info to work it out.
