2 moles of lead gives 2 moles of lead(II) oxide.
1 mole of Pb will give 1 mole PbO
Number of moles = mass/molar mass
Molar mass of Pb =207.2 g/mol
Moles of Pb = 451.4/207.2
= 2.18 moles Pb
Moles of PbO formed = 2.18 moles
Molar mass of PbO = 223.2 g/mol
Mass of PbO formed = 223.2 g/mol × 2.18 mol
= 486.58 g
Percent yield = (actual yield/theoretical yield) × 100
Percent yield =( 363.3/486.58)×100
= 74.66 %
