Calculate the theoretical yield if 100.0 g p4o10 react with 200.0 g h2o

The reaction of Phosphorous Pentaoxide with water yield Phosphoric Acid as shown below,

                             P₄O₁₀  +  6 H₂O   →    4 H₃PO₄

According to balance equation,

           283.88 g (1 mole) P₄O₁₀ requires  =  108 g (6 mole) of H₂O
So,
                          100 g P₄O₁₀ will require  =  X g of H₂O

Solving for X,

                        X  =  (100 g × 108 g) ÷ 283.88 g

                        X  =  38.04 g of H₂O

So, 100 g P₄O₁₀ requires 38.04 g of H₂O, while we are provided with 200 g of H₂O which means that water is in excess and P₄O₁₀ is limiting reagent. Therefore, P₄O₁₀ will control the yield of H₃PO₄. So,
As,
           283.88 g (1 mole) P₄O₁₀ produced  =  391.96 g (4 mole) of H₃PO₄
So,
                          100 g P₄O₁₀ will produce  =  X g of H₃PO₄

Solving for X,
                             X  =  (100 g × 391.96 g) ÷ 283.88 g

                             X  =  138.07 g of H₃PO₄

Result:
           Theoretical Yield of this reaction is 138.07 g.

Following Bob Ewell's attack, Sheriff Tate confirms that Bob died after falling on his own knife. However, Atticus does not believe Sheriff Tate and assumes that Jem is responsible for murdering Bob Ewell after listening to Scout's description of the attack.Essentially, Atticus believes that Jem should take responsibility for murdering Bob Ewell because it is the morally right thing to do, and he fears that his children would have a negative perception of him if he were to cover up Jem's involvement in the murder.
