How many Hg atoms are in 64.0g of HgO?
55.8 grams
What is the romain numeral for HgO?
The Roman numeral for HgO is not applicable. Roman numerals are typically used for representing numbers rather than chemical formulas. HgO is the chemical formula for mercury(II) oxide.
How many moles of mercury (II) oxide are needed to produce 125 g of oxygen?
To determine how many moles of mercury (II) oxide (HgO) are needed to produce 125 g of oxygen (O₂), we first need to consider the decomposition reaction: 2 HgO(s) → 2 Hg(l) + O₂(g). From this equation, we see that 2 moles of HgO produce 1 mole of O₂. The molar mass of O₂ is approximately 32 g/mol, so 125 g of O₂ corresponds to about 3.91 moles (125 g ÷ 32 g/mol). Therefore, since 2 moles of HgO produce 1 mole of O₂, we need 7.82 moles of HgO (3.91 moles O₂ × 2 moles HgO/mole O₂).
Is HgO thermally stable?
Mercury(II) oxide (HgO) is not thermally stable and will decompose upon heating to produce mercury and oxygen gas.
Why is mercuric oxide banned?
Mercury oxide (HgO) is considered to be toxic.
How many grams is 2 moles of HgO?
The molar mass of HgO is approximately 216.59 g/mol. Therefore, 2 moles of HgO would be 2 x 216.59 = 433.18 grams.
How many Hg atoms are in 64.0g of HgO?

How many grams of mercury are produced when 16 grams of HgO are heated?
The molar mass of Hg is 200.59 g/mol and of O is 16.00 g/mol. HgO consists of 1 Hg and 1 O atom, so the molar mass of HgO is 200.59 + 16.00 = 216.59 g/mol. To find the mass of mercury produced, we calculate the molar mass ratio of Hg to HgO: (200.59 g/mol Hg) / (216.59 g/mol HgO) = 0.926. When 16 grams of HgO are heated, the mass of mercury produced would be 16 g * 0.926 ≈ 14.82 grams.
How many grams of mercury and oxygen are formed from 44.5g g of HgO?
To find the molar ratios of Hg and O in HgO, we need to first find the molar mass of HgO: Hg = 200.59 g/mol, O = 16.00 g/mol. HgO = 200.59 + 16.00 = 216.59 g/mol. Next, divide the mass of HgO given (44.5g) by the molar mass of HgO to find the number of moles. Then, use the mole ratio to determine the grams of mercury and oxygen formed.

How many grams of oxygen gas can be formed from the decomposition of 0.437 mol HgO?
By using the balanced chemical equation for the decomposition of mercury(II) oxide (HgO): 2 HgO -> 2 Hg + O2, we see that 1 mol of HgO produces 1 mol of O2. Therefore, 0.437 mol of HgO will produce 0.437 mol of O2. To convert mol to grams, we use the molar mass of oxygen: 32.00 g/mol. so, 0.437 mol of O2 is equivalent to 0.437 mol * 32.00 g/mol = 13.92 grams of O2.
