2 Pb(s) + O2 (g) -----> 2 PbO(s)
2 moles of Pb( 2* 207 g) of lead forms 2 moles of PbO ( 2*223 g
)
414 g Pb forms 446 g PbO
451.4 g Pb will form 451.4 * 446 / 414 = 486.29 g PbO ( this is
theoritical yield)
But actually it formed only 354 g ( this is actual Yield)
% Yield = (Actual yield / Theoritical Yield )* 100
= (354 g / 486.29 g ) * 100 = 72.79 %
