wrong
Apologies for the mistake. Let's break down the equation:
2Hg + O2 → 2HgO
In this equation, we have two mercury atoms (Hg) and one oxygen molecule (O2) on the reactants side. To calculate the total mass, we need to know the atomic masses of mercury (Hg) and oxygen (O).
The atomic mass of mercury (Hg) is approximately 200.59 g/mol.
The atomic mass of oxygen (O) is approximately 16.00 g/mol.
So the total mass of the mercury atoms on the reactants side is 2 x 200.59 g/mol = 401.18 g.
The total mass of the oxygen atoms on the reactants side is 1 x 16.00 g/mol = 16.00 g.
Therefore, the total mass of both mercury and oxygen on the reactants side of the equation is 401.18 g + 16.00 g = 417.18 g.

I apologize for the mistake. Let's try again.
The balanced equation is:
2Hg + O2 → 2HgO
To find the total mass of the mercury and oxygen on the reactants side, we need to calculate the molar masses of each element.
The molar mass of Hg is approximately 200.59 g/mol, and the molar mass of O is approximately 16.00 g/mol.
2Hg x (200.59 g/mol) = 401.18 g
1O2 x (16.00 g/mol) = 16.00 g
So the total mass of mercury and oxygen on the reactants side is 401.18 g + 16.00 g = 417.18 g.
To find the total mass of the Mercury and Oxygen on the reactants side of the equation, we can use 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.
From the balanced equation, we can see that the coefficient of Hg is 2 and the coefficient of O2 is 1.
Given that the total mass of the product, HgO, is 433.2 grams, we can calculate the mass of 1 mole of HgO using the molar mass of HgO. The molar mass of HgO is calculated by adding the atomic masses of Hg and O, which are 200.59 g/mol and 16.00 g/mol respectively.
So, the molar mass of HgO = 200.59 g/mol + 16.00 g/mol = 216.59 g/mol.
To find the number of moles of HgO in 433.2 grams, we divide the mass by the molar mass:
Number of moles = Mass / Molar mass = 433.2 g / 216.59 g/mol.
Now, since the coefficients in the balanced equation represent the ratio of moles, we can multiply the number of moles of HgO (which is 433.2 g / 216.59 g/mol) by the coefficients of Hg and O2 in the balanced equation to find the moles of Hg and O2:
Moles of Hg = 2 * (433.2 g / 216.59 g/mol)
Moles of O2 = 1 * (433.2 g / 216.59 g/mol).
Finally, to find the total mass of Hg and O2 on the reactants side, we multiply the moles of each element by their respective molar masses:
Total mass of Hg = Moles of Hg * Molar mass of Hg
Total mass of O2 = Moles of O2 * Molar mass of O2.
Calculate the values to find the total mass of the Mercury and Oxygen on the reactants side of the equation.
To determine the total mass of Mercury (Hg) and Oxygen (O2) on the reactants side of the equation, we need to calculate the molar masses of both elements and then use stoichiometry to find the corresponding masses.
Mercury (Hg) has a molar mass of 200.59 g/mol.
Oxygen (O2) has a molar mass of 32.00 g/mol.
Using these molar masses, we can calculate the total mass of Mercury by multiplying the molar mass of Hg by the stoichiometric coefficient of 2:
Total mass of Mercury = molar mass of Hg * stoichiometric coefficient
= 200.59 g/mol * 2
= 401.18 g
To find the total mass of Oxygen, we multiply the molar mass of O2 by its stoichiometric coefficient of 1:
Total mass of Oxygen = molar mass of O2 * stoichiometric coefficient
= 32.00 g/mol * 1
= 32.00 g
Therefore, the total mass of Mercury and Oxygen on the reactants side is:
Total mass of Mercury + Total mass of Oxygen = 401.18 g + 32.00 g
= 433.18 g
So, the total mass of Mercury and Oxygen on the reactants side of the equation is 433.18 grams.
