If the total mass of the product, mercuric oxide, HgOis 433.2 grams, what is the total mass of the Mercury and Oxygen on the reactants side of the equation?

Question

Type your answer in the below box.

Answer 1

The molar mass of mercury (Hg) is 200.59 g/mol, and the molar mass of oxygen (O) is 16.00 g/mol.

Since the formula of mercuric oxide is HgO, we can calculate the molar mass of HgO as 200.59 + 16.00 = 216.59 g/mol.

To find the total mass of mercury and oxygen on the reactants side of the equation, we need to multiply the molar mass of HgO by the number of moles present in 433.2 grams.

Total mass = (molar mass of HgO) * (number of moles)
Total mass = 216.59 g/mol * (433.2 g / 216.59 g/mol)
Total mass = 433.2 grams

Therefore, the total mass of mercury and oxygen on the reactants side of the equation is 433.2 grams.
