The percent yield when a reaction vessel that initially contains 65.5 kg ch4 and excess steam yields 15.0 kg h2 is 45%.

Percent yield is a calculation that compares how an awful lot product we surely produce with how an awful lot product that we calculate that we need to produce. In each response in a actual lab, we can usually produce a piece much less product than we calculate.

Percent yield measures how near we will get.The percentage yield is 45 %.

CaCO₃ →CaO + CO₂

First, calculate the theoretical yield of CaO.

Theor. yield = 60 g CaCO3×1 mol CaCO3100.zero g CaCO3×1 mol CaO1 mol CaCO3×56.08 g CaO1 mol CaO=33.6 g CaO

Now calculate the percentage yield.

% yield = real yieldtheoretical yield×100%=15 g33.6 g×100%=45%.
