What is a formula of Potassium Sulfate?

First, look at the Periodic Table. Potassium is in group 1 so has a +1 charge,  Li+

Sulphates always have a -2 charge, SO4 2-

Now combine two ions together so we can get a neutral compound. We have +1 charge on Li ion and -2 charge on SO4 ion. Therefore, we need two Li+ ions for one SO4 2-

Now the charges cancel out and we have a neutral salt Li2SO4
