Calculate the number of atom in 13.2 mol copper?
To calculate the number of atoms in 13.2 mol of copper, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply 13.2 mol by Avogadro's number to get the number of atoms: 13.2 mol * (6.022 x 10^23 atoms/mol) = 7.93 x 10^24 atoms. Therefore, there are approximately 7.93 x 10^24 atoms in 13.2 mol of copper.
Which element has a greater atomic mass silver or copper?
Silver has a greater atomic mass than copper. The atomic mass of silver is approximately 107.87 g/mol, while the atomic mass of copper is approximately 63.55 g/mol.
How many atoms of phosphorus are in 8.90 mol of copperII phosphate?
To find the number of phosphorus atoms in 8.90 mol of copper(II) phosphate (Cu₃(PO₄)₂), we first identify that each formula unit contains 2 phosphorus (P) atoms. Thus, in 8.90 mol of copper(II) phosphate, the total number of phosphorus atoms is calculated as follows: 8.90 mol × 2 P/mol = 17.8 mol of phosphorus atoms. To convert moles to atoms, we multiply by Avogadro's number (approximately (6.022 \times 10^{23}) atoms/mol): 17.8 mol × (6.022 \times 10^{23}) atoms/mol ≈ (1.07 \times 10^{24}) phosphorus atoms.
What is the mass of CuCl?

How many moles of copper will be produced if 5.8 mol of Zn react with excess copper II sulfate?
Also 5,8 mol
How many moles of copper will be produced if 5.8 mol of zinc react with excess copper (ll) sulfate?
If zinc reacts with excess copper(ll) sulfate, a 1:1 molar ratio will be maintained. Therefore, 5.8 mol of zinc will produce 5.8 mol of copper.
How many atoms of phosphorus are in 3.30 mol of copper (ll) phosphate?
There are 1 mol of phosphorus atoms in 1 mol of copper (II) phosphate. Therefore, in 3.30 mol of copper (II) phosphate, there are 3.30 mol of phosphorus atoms, which is equivalent to 3.30 x 6.022 x 10^23 = 1.97 x 10^24 atoms of phosphorus.
What weight in g is 0.252mol of copper?
To find the weight of 0.252 mol of copper, you need to multiply the number of moles by the molar mass of copper. The molar mass of copper is approximately 63.55 g/mol. Therefore, 0.252 mol of copper would weigh approximately 15.99 grams.
How many atoms are in 6.4g of copper?
To determine the number of atoms in 6.4g of copper, you first need to find the number of moles using the molar mass of copper (63.55 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms. The final calculation would be: (6.4g / 63.55g/mol) * 6.022 x 10^23 atoms/mol.
What is the mass in grams of atom of copper and how many atom are there 1g of copper?
6.022*10**23 atoms / mol = avagadro's constant 63.546 g / mol = atomic weight of copper 1 atom / 6.022*10**23 atoms/mol * 63.546 g/mol = 1.05523082*10**-22g 1 g / 63.546 g/mol * 6.022*10**23 atoms/mol = 9.476599629*10**21 atoms
What is the mass of 4.75 mol of copper (II) nitrate?
To calculate the mass of 4.75 mol of copper (II) nitrate, you need to first find the molar mass of Cu(NO3)2 which is 187.55 g/mol. Then, multiply the molar mass by the number of moles (4.75 mol) to get the mass: 187.55 g/mol * 4.75 mol = 890.56 grams. So, the mass of 4.75 mol of copper (II) nitrate is 890.56 grams.
How much does 2.18 mol of Cu weigh?
The molar mass of copper (Cu) is approximately 63.55 g/mol. To calculate the weight of 2.18 mol of copper, you would multiply the number of moles by the molar mass: 2.18 mol x 63.55 g/mol ≈ 138.49 g. Therefore, 2.18 mol of copper weighs approximately 138.49 grams.
How many atoms of phosphorus are in 4.40 mol of copper(II) phosphate?
There are 1 atom of phosphorus in each formula unit of copper(II) phosphate, which is Cu3(PO4)2. Therefore, in 4.40 mol of copper(II) phosphate, there are 4.40 mol of phosphorus atoms, which is 4.40 x 6.022 x 10^23 atoms.
How many atoms are in 1 mole of Copper?
1 mol Cu Atoms (6.02x10^23 atoms)
Calculate the number of atoms in 13.2 mol copper.?
b. 7.95 ´ 1024 atoms
How many atoms would be found in 1.2 grams of copper?
To find the number of atoms in 1.2 grams of copper, you need to first determine the molar mass of copper (Cu). The molar mass of copper is 63.55 g/mol. Next, calculate the number of moles in 1.2 grams of copper (1.2 g / 63.55 g/mol = 0.0189 mol). Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms: 0.0189 mol x 6.022 x 10^23 atoms/mol = approximately 1.14 x 10^22 atoms.
