calculate the molar mass of CaSO3.
Then divide the molar mass of Ca by the molar mass of CaSO3, then multiply by 100 to make it a percentage.
Do the same for S and for O.

To solve this you will have to make an asumption: consider that you have 100g of CaSO3. Another tip that will help you is that the molecular formula of a compound tells you its composition when based in moles. So for example, if you have a compound A2B3, then 1 mol of A2B3 contains 2moles of A and 3 moles of B. Given that you have 100g of CaSO3, you can ultimately determine how many moles (and from there grams) of each of the compounds you are looking for.
Good luck!
