Answer:
71.5 %
Explanation:
mercury + bromine ⟶ compound
Mass/g: 60.2 24.0
According to the <em>Law of Conservation of Mass</em>, the mass of the product must equal the mass of the reactants
Mass of product = 60.2 + 24.0
Mass of product = 84.2 g
The formula for <em>percent composition</em> is
% by mass = mass of component/total mass × 100 %
% Hg = 60.2/84.2 × 100
% Hg = 0.7150 × 100
% Hg = 71.5 %
