The number of atoms in a given mass of metal may be calculated by dividing the mass by the gram Atomic Mass, then multiplying by Avogadro's Number. The gram atomic masses of iron and copper are 55.847 and 63.546 respectively. Since Avogadro's Number is constant, the required mass m of copper atoms can be found from the equation m/63.546 = 235/63.546, or m = 235 X (63.456/55.847), or 267 grams of copper, to the justified number of significant digits.

What is the number of atom in 13.2 moles of copper?
The number of copper atoms is 79,49.10e23.
How many moles of copper atoms do you have if you have 1.2x1048 copper atoms?
To find the number of moles of copper atoms, divide the number of copper atoms by Avogadro's number (6.022 x 10^23). Therefore, for 1.2 x 10^48 copper atoms, the number of moles is 1.99 x 10^24 moles.
What is used to describe the number of atoms in a copper penny?
The term "Avogadro's number" is used to describe the number of atoms in a copper penny. This number is approximately 6.022 x 10^23, which represents the number of atoms in one mole of any substance.
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.
Is copper an element which is made up of atoms?
Yes, copper is an element that is made up of atoms. Each copper atom contains the same number of protons in its nucleus, giving it unique chemical properties that define it as copper.
How many copper atoms are in a pure copper statue with a mass of 148kg?
To find the number of copper atoms in the statue, you need to first determine the number of moles of copper using its molar mass. Then, you can multiply the number of moles by Avogadro's number to find the number of atoms. Given that the molar mass of copper is approximately 63.55 g/mol, you can follow these steps to calculate the number of copper atoms in the statue.
What is the number of atom in 13.2 moles of copper?
The number of copper atoms is 79,49.10e23.
If a sample of copper contains 1.76E 4 atoms of copper-63 and 7.88E 3 atoms of copper-65 what is the percentage of copper-63 atoms in the sample?
To find the percentage of copper-63 atoms in the sample, first add the number of copper-63 and copper-65 atoms together (1.76E4 + 7.88E3). Then, divide the number of copper-63 atoms by the total number of atoms and multiply by 100 to get the percentage. In this case, the percentage of copper-63 atoms in the sample is approximately 69.0%.
If you have 1.81 10 24 atoms of copper how may moles of copper do you have?
Take that number of copper atoms and divide by "Avogadro's constant," which is the number of representative particles (in this case, atoms) in 1 mole of any substance. Here's the math: 1.8x10e24 / 6.02x10e23 = approximately 3 moles.
What mass of copper contains the same number of atoms as 68.7 g of iron?
To find the mass of copper containing the same number of atoms as 68.7 g of iron, we need to first calculate the number of atoms in 68.7 g of iron using its molar mass. Then, we convert this number of atoms to copper atoms using the ratio of their molar masses. Finally, we determine the mass of copper corresponding to this number of atoms.
How many moles of copper atoms do you have if you have 1.2x1048 copper atoms?
To find the number of moles of copper atoms, divide the number of copper atoms by Avogadro's number (6.022 x 10^23). Therefore, for 1.2 x 10^48 copper atoms, the number of moles is 1.99 x 10^24 moles.

How many atom in 6.35 g of copper?
To find the number of atoms in 6.35 g of copper, you first need to determine the number of moles of copper present by dividing the mass of copper by its molar mass (63.55 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that number of moles.
How many moles of copper are equivalent to 3.44x10 to the 23 power atoms of copper?
To find the number of moles of copper, divide the number of atoms by Avogadro's number (6.022 x 10^23). Therefore, 3.44 x 10^23 atoms of copper is equivalent to 0.571 moles of copper.
How many copper atoms are in 2.36 of copper?
To find the number of copper atoms in 2.36 g of copper, first convert the mass to moles using the molar mass of copper (63.55 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. So, there are approximately 2.36 x 6.022 x 10^23 atoms of copper in 2.36 g.
How many atoms are in copper phosphate?
Copper phosphate has the chemical formula Cu3(PO4)2. To determine the number of atoms, you need to add up the atoms in each element present. In this case, there are 3 copper atoms, 2 phosphorus atoms, and 8 oxygen atoms, totaling 13 atoms in copper phosphate.
In a sample of pure copper all atoms have the same what?
In a sample of pure copper, all atoms have the same number of protons, which determines the element's identity.
