It takes 8 steps for an enzyme inhibitor to be synthesized. If each step gives a 67.0% yield, what is the final % yield?

When 24.60 g C₃H₆ and 56.90 g Cl₂ react, it produces an actual yield of 32.40 g C₃H₅Cl.

C₃H₆ + Cl₂  → C₃H₅Cl + HCl

What is its % yield?

The reaction between SO₂ and O₂ produces SO₃ with a yield of 55%. For the mixture shown below, determine the number of molecules for each compound after the reaction

Yellow spheres are S atoms and green spheres are O atoms.

The following reaction has a yield of 96%.

2 H₂Se + 3 O₂ → 2 SeO₂ + 2 H₂O

Determine the mass of SeO₂ produced if 20.0 g of H₂Se and 40.0 g of O₂ were reacted

5.69 g of ammonia is produced when a sample of hydrogen reacts with excess nitrogen. The balanced reaction is shown below: 

   3 H₂(g) + N₂ (g) → 2 NH₃ (g)

Calculate the theoretical yield if the percent yield is 38.25%.
