How many grams of sulfur are in 3.45g of H2S?

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! :)
