How many copper atoms are in a pure copper statue with a mass of 133 kg?
1.26 X 10^27
How many atoms are in a sample of copper with a mass of 18.46?
17.48 atoms
How many atoms are in a sample of copper with a mass of 18.46 grams?
17.48 atoms
How many atoms of copper equal a mass of 127.10 g?
1.20 × 1024 atoms
How many copper atoms are in pure coin the size of a penny?
This depends on the mass of this penny.Number of atoms = [(Mass of the coin) x 6,022.10e23]/63,546.
What is the mass of 4 atom(s) of copper in grams?
The mass of 4 copper atoms is 4,2208.10e-22.
How many atoms in 54.6 g of copper?
5.18 X 1023 : The gram atomic mass of copper is 63.546, and by definition Avogadro's Number of atoms is contained in the gram atomic mass. Therefore, the number of atoms in the stated mass is (54.6/63.456) X 6.022 X 1023.
What mass of copper contains the same number of atoms as 68.7 g of iron?
The mass of copper is 78,17 g.
A sample of copper with a mass of 63.5 g contains 6.02x1023 atoms calculate the mass of the single copper?
10.5 * 10^-21
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 atoms are in 1 kg mass of copper?
1 kg Copper = 1000 g Copper1000 g copper x 1 mole copper/63.5 g x 6.02x10^23 atoms/mole = 9.48x10^24 atomsAnswer would be 9x10^24 atoms to 1 significant figure
