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.

Why does a mole of copper atoms weigh less than a mole of lead atoms?

Because copper has a smaller molar mass, hence it will have less mass per mole than lead.

How do you convert 2.11x10 to the 24 atoms of copper to mass in grams?

2.11x10^24 atoms... Divide by Avogadro's Constant (6.02x10^23 particles/mole) Gives you moles of copper... Multiply by the molar mass of copper. (?? g/mol) Gives you grams of copper...

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.

How many copper atoms does it contain The volume of a sphere is 43pieR3 and the density of copper is 8.96 gcm3 A pure copper sphere has a radius 0.936 in?

Use your volume formula and your radius to find volume. Next use the equation d=m/v or m=dv to find your mass of copper. Use your mass, atomic weight of copper, and avagadro's number to figure out your atoms.

How many atoms are there in a 1cm cube of copper?

Find the mass of 1 cm3 of copper.density= mass / volumemass= density * volume (density is about 8.96 g cm-3)mass= 8.96 g cm-3 * 1 cm3 = 8.96 gno. of moles = mass / Molar mass =8.96 g / 63.5 g mol-1 = 0.14 molno. of copper atoms in 1 cm3 of copper= 0.14 mol * 6.022 *1023 =8.4 * 1022 atoms

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.
