If you have three moles of S2, how many moles of Al2S3 can be produced?

Question

11. If you have three moles of S2, how many moles of Al2S3 can be produced?
12. If you have 18.5 moles of Al, how many moles of S2 do you need to react with all of the aluminum?
13. If you had 24 moles of hydrogen gas how many moles of ammonia (NH3) would be produced?

To produce Al2S3, the balanced chemical equation is:

2 Al + 3 S2 → Al2S3

From the equation, 3 moles of S2 produce 1 mole of Al2S3. Therefore, 3 moles of S2 will produce 1 mole of Al2S3.
Using the balanced equation 2 Al + 3 S2 → Al2S3, 2 moles of Al react with 3 moles of S2. Therefore, for 18.5 moles of Al, you need:

(18.5 moles Al) * (3 moles S2 / 2 moles Al) = 27.75 moles of S2.
The balanced equation for the production of ammonia is:

N2 + 3 H2 → 2 NH3

From the equation, 3 moles of H2 produce 2 moles of NH3. Therefore, 24 moles of H2 will produce:

(24 moles H2) * (2 moles NH3 / 3 moles H2) = 16 moles of NH3.
