How many atoms of (Hg) are in 200.6g and 400.1g?
The molar mass of mercury (Hg) is 200.59 g/mol. In 200.6g, there would be 1 mole of Hg, which is equal to 6.022 x 10^23 atoms. In 400.1g, there would be 2 moles of Hg, which is equal to 1.2044 x 10^24 atoms.
How many atoms are in the 1.25x10 mol of mercury within the bulb of a thermometer?
To find the number of atoms in 1.25x10^4 mol of mercury, you need to use Avogadro's number, which is 6.022x10^23 atoms/mol. Multiply the number of moles by Avogadro's number: 1.25x10^4 mol * 6.022x10^23 atoms/mol = 7.5275x10^27 atoms in 1.25x10^4 mol of mercury.
How many atoms are there in Hg2Cl2?
There are 5 atoms in Hg2Cl2: 2 mercury atoms (Hg) and 3 chlorine atoms (Cl).
What is the molecular weight of Hg?
The molecular weight of mercury (Hg) is approximately 200.59 g/mol.
According to the balance equation 2Co plus 3 Hg Cl2 equals 2 Co Cl plus 3Hg How many grams of mercuric chloride must react to give 5.11g of mercury?
To calculate the grams of mercuric chloride needed, we must first find the molar mass of HgCl2 (molar mass = 200.59 g/mol). Then, calculate the moles of mercury in 5.11g (moles = 5.11g / molar mass of Hg = 0.032 mol). Since the ratio of HgCl2:Hg is 3:1 in the balanced equation, you would need 0.032 mol of HgCl2 (0.032 mol Hg x 1 mol HgCl2 / 1 mol Hg = 0.032 mol HgCl2) which is equal to 6.42g of HgCl2 (0.032 mol HgCl2 x molar mass of HgCl2 = 6.42g).
How many atoms of (Hg) are in 200.6g and 400.1g?
The molar mass of mercury (Hg) is 200.59 g/mol. In 200.6g, there would be 1 mole of Hg, which is equal to 6.022 x 10^23 atoms. In 400.1g, there would be 2 moles of Hg, which is equal to 1.2044 x 10^24 atoms.
How many atoms are in 11.5 g Hg?
To find the number of atoms in 11.5 g of mercury (Hg), first determine the number of moles using its molar mass, which is approximately 200.59 g/mol. Divide the mass by the molar mass: ( 11.5 , \text{g} \div 200.59 , \text{g/mol} \approx 0.0573 , \text{mol} ). Then, multiply the number of moles by Avogadro's number ( (6.022 \times 10^{23} , \text{atoms/mol}) ): ( 0.0573 , \text{mol} \times 6.022 \times 10^{23} \approx 3.45 \times 10^{22} ) atoms. Thus, there are approximately ( 3.45 \times 10^{22} ) atoms in 11.5 g of Hg.

55.8 grams
How many grams of sulfur are needed to react with 246grams of Hg to form HgS?
The balanced chemical equation for the reaction is Hg + S -> HgS. The molar mass of Hg is 200.59 g/mol and HgS is 232.66 g/mol. To form 1 mol of HgS, 1 mol of S is required. Calculate the amount of S needed using the given mass of Hg.
How many moles of atoms are in 12.0 gram of helium?
For this you need the atomic mass of Hg. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. 12.0 moles Hg × 200.6 grams = .0598 grams Hg
What is the molecular weight of Hg?

According to the balance equation 2Co plus 3 Hg Cl2 equals 2 Co Cl plus 3Hg How many grams of mercuric chloride must react to give 5.11g of mercury?
To calculate the grams of mercuric chloride needed, we must first find the molar mass of HgCl2 (molar mass = 200.59 g/mol). Then, calculate the moles of mercury in 5.11g (moles = 5.11g / molar mass of Hg = 0.032 mol). Since the ratio of HgCl2:Hg is 3:1 in the balanced equation, you would need 0.032 mol of HgCl2 (0.032 mol Hg x 1 mol HgCl2 / 1 mol Hg = 0.032 mol HgCl2) which is equal to 6.42g of HgCl2 (0.032 mol HgCl2 x molar mass of HgCl2 = 6.42g).
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.
