1. Find the molar mass of H2S
2. From this, find the number of moles of H2S that you have in 3.45 g of H2S
3. If you have such number of moles of H2S, how many moles of S do you have?
4. Using that number of moles of S, take the relative atomic mass of S and work out the mass of this number of moles of S.
Post what you get! :)
