To find the mass of 2 moles of mercury(II) oxide (HgO), we first need to know the molar mass of HgO.
The molar mass of Hg (mercury) is approximately 200.59 g/mol, and the molar mass of O (oxygen) is about 16.00 g/mol. Therefore, the molar mass of HgO can be calculated as follows:
- Molar mass of HgO = Molar mass of Hg + Molar mass of O
- Molar mass of HgO = 200.59 g/mol + 16.00 g/mol = 216.59 g/mol
Now, to find the mass of 2 moles of HgO, we use the formula:
Mass = Moles × Molar Mass
Substituting the values:
Mass = 2 moles × 216.59 g/mol = 433.18 g
Thus, the mass of 2 moles of HgO is 433.18 grams.
