Let MM(x) be the molar mass of x.
MM(Pb) : MM(PbO)
=207.21 : 223.20 = 451.4 g : x g
cross multiply and solve for x
x=223.2/207.21*451.4
= 486.23 g
Percentage yield = 365.0/486.23= 0.75067 = 75.07% (rounded to 4 sign. fig.)

I JUST TOOK THE QUIZ!!!!
<span>A Homogeneous Catalyst exists in the same physical state as that of the reaction it catalyzes.
Explanation:
Catalysts are classifies as follow,
1. Homogeneous Catalyst
2. Heterogeneous Catalyst
</span>Homogeneous Catalyst are those which are in same phase as that of reactants are.
Example:
Acetic Acid + Ethanol + H₂SO₄ → Ethyl Acetate + H₂O + H₂SO₄
In this reaction catalyst and reactants all are in same phase i.e. Liquids.
Heterogeneous Catalyst are those which are in different phase as that of reactants are.
Example:
Ethene + H₂ + Ni → Ethane + Ni
In this reaction ethene and hydrogen are gases while Nickle catalyst is in solid state.
