The total mass of the reactants can be determined by using the Law of Conservation of Mass. According to this law, the total mass of the reactants must be equal to the total mass of the products.
In this balanced chemical equation, the coefficient of Hg (mercury) is 2, and the coefficient of O2 (oxygen) is 1.
To calculate the mass of mercury, we multiply the coefficient of Hg (2) by its atomic mass (around 200.59 g/mol).
Mass of mercury = 2 * 200.59 g/mol = 401.18 g
To calculate the mass of oxygen, we multiply the coefficient of O2 (1) by its atomic mass (around 32.00 g/mol).
Mass of oxygen = 1 * 32.00 g/mol = 32.00 g
Therefore, the total mass of mercury and oxygen on the reactants side of the equation is:
Total mass = mass of mercury + mass of oxygen
Total mass = 401.18 g + 32.00 g
Total mass = 433.18 g
So, the total mass of mercury and oxygen on the reactants side of the equation is approximately 433.18 grams.

I apologize for the mistake. Let's calculate it correctly.
In the balanced chemical equation 2Hg + O2 -> 2HgO, we have 2 moles of Hg reacting with 1 mole of O2 to form 2 moles of HgO.
To find the total mass of mercury and oxygen on the reactants' side, we need to determine the molar masses of Hg and O2.
The molar mass of Hg is approximately 200.59 g/mol.
The molar mass of O2 is approximately 32.00 g/mol. Note that O2 exists as a diatomic molecule in this reaction.
Given that we have 2 moles of Hg, the mass of Hg is calculated as follows:
Mass of Hg = 2 moles Hg * 200.59 g/mol
Mass of Hg = 401.18 g
Given that we have 1 mole of O2, the mass of O2 is calculated as follows:
Mass of O2 = 1 mole O2 * 32.00 g/mol
Mass of O2 = 32.00 g
The total mass of mercury and oxygen on the reactants' side is:
Total mass = Mass of Hg + Mass of O2
Total mass = 401.18 g + 32.00 g
Total mass = 433.18 g
So, the total mass of mercury and oxygen on the reactants' side of the equation is approximately 433.18 grams.
