    2 HgO → 2 Hg + O₂

    (2 x 216.59 g) → gives → (2 x 200.59 g)

    433.18 g → gives → 401.18 g

    8.74 g → gives →? g

    by cross multiplication:

    Theoretical yield = (401.18 x 8.74) / 433.18 = 8.094 g

    % yield = (actual yield / theoretical yield) * 100

    = (6.42 / 8.09) * 100 = 79.3 %
