SOLVED: Mercury(II) oxide (HgO) decomposes to form mercury (Hg) and oxygen (O2). The balanced chemical equation is shown below: 2HgO → 2Hg O2. The molar mass of HgO is 216.59 g/mol. The molar mass of O2 is 32.00 g/mol. How many moles of HgO are needed to produce 250.0 g of O2?

Calculate the mass of oxygen released when enough mercury(II) oxide decomposes to give 25 grams of liquid mercury. 2 HgO(s) ⟶2 Hg(l) O2(g) | Numerade
