How many copper atoms are in a pure copper statue with a mass of 129 kg?
The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
How many copper atoms are in a pure copper statue with a mass of 133 kg?
To calculate the number of copper atoms in the statue, you first need to find the moles of copper present in 133 kg using its molar mass. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of copper to atoms.
How many grams of copper could you get from 30 grams of aluminum?
None, as pure Aluminium is an element which contains only atoms of Aluminium and nothing else.
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
How many atoms in 8 grams of copper?
To find the number of atoms in 8 grams of copper, you first need to determine 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 convert moles to atoms.
How many copper atoms in a penny made of pure copper and weight 2.15g?
A penny made of pure copper has a mass of 2.5g and an atomic mass of copper is 63.55 g/mol. Calculate the number of moles in 2.5g of copper, then use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of copper atoms. This calculation would yield approximately 1.44 x 10^22 copper atoms in a penny.
How many dozens of copper atoms in a penny?
A US 1 cent piece prior to 1982 was made of copper and had a mass of about 3.1g. This is about 0.049 moles of copper, or around 2.9 x 1022 atoms. More recent pennies are mostly zinc (97.5%) and have a mass of about 2.5g. This works out to around 2.2 x 1022 zinc atoms and 5.9 x 1020 copper atoms, so overall around 2.3 x 1022 atoms.
How many moles of atoms are in 4.5 grams of Cu?
4,5 moles of copper are equivalent to 285,957 g.
How many atoms are there in a copper and what are they?
Copper is an element. You can have a single atom or many atoms and it's still copper.
How many atoms of copper are there in a pure copper cion weighing 12.0 grams?
The molar mass of copper is 63.5 g/mol. Using this, you can calculate that in a 12.0 gram sample of copper, there are approximately 0.189 moles of copper. Since 1 mole of a substance contains 6.02 x 10^23 atoms (Avogadro's number), the number of atoms in 0.189 moles of copper would be around 1.14 x 10^23 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.
How many grams of copper atoms are needed to supply the same number of atoms as does 235 grams of iron?
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.
