Chemistry - Mass Ratio, Atoms and Density
If 2.40 cm3 of Ba reacts with 1.65 cm3 of S, are there enough Ba atoms to react with the S atoms (d of Ba = 3.51 g/cm3; d of S = 2.07 g/cm3)?
For barium sulfide, calculate the barium to sulfur mass ratio.

Determining chemical formula
If we assume we've got 100 grams of the substance, then we'd have 40.7 g C, right?
How many moles is that?
(40.7 g)(1 mol/12 g) = 3.39 mol
In 100 g, we'd have 54.2 g oxygen, right? How many moles is that?

Problems Regarding Organic Chemistry Reactions
Therefore, statements A,B, & C are all wrong. All of the H2S will be used up because its the limiting reagent.
Therefore, we need to determine how much sulfur is formed.
2 moles of H2S react to produce 3 moles of S.
